I'm trying to import a bunch of songs to my laptop but most of the songs fail. I've tried using the regular osu list file too and reinstalling both osu and osu!Sync. I've also tried different mirror in the import section and they fail as well.

Osu!Sync will say that ever beatmap is 'invalid' and give me the option to either skip it or cancel the whole download. Saying 'Yes' will cause it to hang for a bit before saying the same dialog for the next one, and so on and so forth. Saying 'No' will just make it cancel the download.

osu!Sync Version 1.0.0.8

When downloading songs which doesn't exits from bloodcat.

All the download report successful

Creates file with

* File not found or inaccessible!

in the osu! song directory.

• Titles should never end with a period. Besides the titles, this also goes for:
  • Checkbox labels and any labels in general (including buttons);
  • Window titles;
  • Dropdown list items;
  • Status messages ("Please sync." and so forth).
• "Get Beatmap Sets" is unclear, perhaps it should be "Sync" since you're asking a user to sync everywhere else.
• Using the same string "Installed" for both category's name and status label ("Installed?") is not really good, wording of these two may differ among the languages.
• I have a strange feeling I see your application's name way too often when browsing the interface, consider reducing its usage to main window's title and one or two occurences in "About".
• In Updater window, there's "version" word popping up too often.
• Finally, see my note on Approved category: https://crowdin.com/translate/osusync/3/en-ru#q=approved

Crashes after download. Opening the app again prompts the update again, and again it crashes.

Not sure how important this is, but I figured I'd say something

When I downloaded the zip file from the release and replaced the old files, it still was 1.0.0.3

1. Report
This bug has been reported through the feedback window

Would be nice to add another progress bar and title it "Interface generation". However, I suspect it won't be that much of a problem, once you're done with #24.

Is this suppose to happen?

"Select some beatmaps to export" → "Export" done a few times leads to:

Report
osu!Forum

Unless I'm just very impatient, the updater doesn't seem to work. It notifies me of an update just fine, and then downloads it. It asks me if I want to clear the folder, and I say yes. After that it just sits at "Verified Update Package" for a while, with the loading bar still moving, and the 'loading' mouse icon when you mouse over it. Apologies for no screenshots, but the folder's empty, and I can only download the updated version.
UPDATE: Tried it on another computer and it worked flawlessly. Only thing that changed was the OS (worked on win7, not on win8.) Sorry if that's not very helpful.

Saving Download Mirrors in an external file makes it more easy to add new ones and allows to update the list seperately from the application.

Setting the osu! path and clicking "Get Beatmap Sets" causes this error and a crash:

Since bloodcat is offline I switched to the other mirror in the settings (osu.uu.gl) and was going to download a bigger set of maps (about 1,5k) when first, a "b-baka"-Exception window popped up mutliple times, then a Notepad with exception infos opened and the program crashed. I tried this 3 times with the same result. Here are the details:

Whether I'm running as admin or not. Tried completely deleting files and appdata, downloading again, and running but it does the same thing. The weird part is it worked once, then I tried to export something and now when I try to sync again it crashes.

Could you try to optimize the program a bit? it makes my taskmgr look like this http://killhim.php5.cz/betaweb/img/2016-01-04_18-47-32.png - i would do it myself but vb is not my language really

I tied downloading from osu.uu.gl and Hexide, witch both game me an error (cant retrieve data, or something).
So I switched to Ripple.
That seemed to work at first, but I got "b-baka - Exception"s for every downloaded beatmap and after 6 maps, the screen was full of b-baka exceptions and the program froze.

The crash log is attached.
2018-08-25 18.48.50.txt

So I can basically no longer use Osu!Sync at the moment....

When I try to download any maps, osu!sync crashes. Here's my error log (the song that caused the crash was xi - .357 magnum by Akali)

Maybe include into updater?

Why not use the osu default server?

Bloodcat now requires a captcha before allowing to download.

I went to update from 0.0.0.9 to 0.0.0.10 on my Win8 laptop, and it was stuck at "Moving Files."
I went to the temp folder to see if I could just manually copy the files, but the only thing there was the Update Patcher

• Implement Hash check

Provide a way to automatically update translations and maybe mirrors (#41) without having to update the application itself.

I get this when trying to update, telling me that it can't find the temp file for the update. I can still do it manually though.

Requested by Andrey

I'm not sure if this even constitutes a bug report, but here we go...
I've noticed, for a while, that the scroll bar on the side of the window is sometimes tricky to grab. The reason being that, after a certain point (about 1/4th of the way across it) my mouse turns into the resize icon and can no longer be grabbed. This happens both on my Win7 Computer and my Win 8.1 Laptop
Unfortunately, Puush doesn't let me screen cap my mouse, so I can't really provide screen shots, but it's easy to reproduce.
