The launcher is horrible I don't even know what to tell you. It hasn't been working in 6 months.
I guess that's one way to make people stick to DRM publishers.

Deleted the app deleted the cache cleaned the registry several reboots tried this tried that never had an issue with any other game client. This is a first.

Horrible.

You'll be glad to hear, you don't even need the galaxy client to access your games.

Select your game
Ignore the blue galaxy client banner.
Below that, is the normal game installers. Use them.

Problem solved!

It's not a Galaxy 2.0-specific issue, since it happens with Galaxy 1.2 as well.

Must be an issue with GOG's servers or something like that, rather than the software itself.
