plvary: I'm having trouble with Cyberpunk 2077 as well. I tried to update it, it said my copy was "corrupted" so I uninstalled, went to reinstall, it said "server problem", so I installed through my offline backup, and tried to update again. It told me the same thing again about corrupted copy and then after uninstalling it it's said server problems when trying to reinstall it the regular way. What's going on? It seems to only do this with my bigger games that are over 50GB or so.
It's not only big games over 50GB. GOG Galaxy is completely bonked right now. I've had this problem with Hero's Hour (a 300MB game) and DeusEx GOTY (3GB game). The solution I found is to download the offline installer, make the installation yourself, and then scan for GOG games in your launcher.
