That's odd. 🤔

You can probably bypass the bug and start the app by setting CheckForUpdates=false in BandcampDownloader.ini.

Let me know what happens.

Yep, Otiel, that worked perfectly! :) Could not retrieve data is now on anything I want to DL? So App launches but can't DL anything?

bulletremedy commented 2 years ago

How Odd though? It's gotta be my system only, because it happens on every version, from today only? I wonder what's messing your app up on my system? Check for Updates false works though. Thank you very much.

Did you install or uninstalling something on your computer?

Is there some software, anti-virus, proxy that could block BandcampDownloader?

bulletremedy commented 2 years ago

No nothing installed or uninstalled, I'm starting to think it's a .NET framework bug or error, because Wondershare uniconverter also not working, just won't launch, the issue is here, only a fresh install will fix even if i uninstall .NET windows still thinks its installed, so far these are the only two apps that are not working though?

Got me stumped. Firewall on or off, doesn't change a thing even with rules accepting the app and I even tried uninstalling my antivirus and disabling defender with defender control, GPedit and reg, but still no luck?

This for me is a real head scratcher ???

Otiel commented 2 years ago

I'm not sure I understand. Did you try reinstalling .NET Framework 4.8?

bulletremedy commented 2 years ago

I thought it was a .NET issue but no, I reinstalled all .NET services still the App isn't working??? Stumped, cannot pinpoint whee it could be going wrong?

Otiel commented 2 years ago

Can you try this build and share the log file?
