Vainamoinen: RTG is now aware of the problem. Ye-haaa. :|
It seems like they've been scanning the Steam forums 24/7 and all through the holidays, but not the GOG or even their own support forums.
Errr.... well, they've vowed to do better in the future, that's something. ;)
We have been checking emails, tweets and our own forum during the Christmas holidays — but unfortunately we (and *I*) missed the thread about the patch 4.1.1 problems here on GOG. I can only blame myself for that, so feel free to direct your yelling in my direction!
We're in touch with GOG about the issues, and it appears the 4.1.1 patch results in a corrupted install. This needs to be fixed on GOG's side — they make all the patches — so hopefully that will happen today. We'll be following up.
We apologise again to our customers for this screw-up. We're not happy about leaving you guys without a working game for so long. Hopefully you'll all be able to continue playing before the end of the day!
