When I load up GOG Galaxy, after a few seconds is closes without warning. There's no error popup or anything. I don't understand what's wrong with it, as it was working fine up until a few days ago. I've tried uninstalling and reinstalling, but it still does the same thing. I don't know what else to try. Does anyone have any suggestions?

Best thing would be to post in the galaxy thread and also on mantis with your logs (how to do that is in the first post):

Also no need to open several threads for this ;-)

Cheers for the response. My first thread disappeared into the depths of the second page pretty quickly, so I reposted it as a question in the hope it'd get a response.

I posted in that mantis thing, but my post was removed...
