jtgizmo: Ok I am now at witts end. Ever since I closed gog down mid download for Witcher 3 patch 1.10 (I had to go so had to shut everything down) GOG no longer launches for me.

This is the funny thing - when I reinstall it gog comes up and is up and running straight away, but when I connect to GOG (log in to my account) it loggs in and then disappears - it minimizes to task bar and then disappears from taskbar also. If I click on GOG shortcut again nothing happens. In Task Manager I can see process is running but I can't see GOG itself. I've tried rebooting, I've tried reinstalling to different folders. Still nothing - can anyone please recommend what to do? It seems to be working if I am not logged into GOG but the moment I log in/connect it shuts down.

jtgizmo: Yeah I did that. I even uninstalled it, rebooted my pc, downloaded fresh client and then installed it - and then ran the client, after logging in - it closed down.
