Ciris: The problem here is that we introduced a universal CD Key of sorts into the game so that it would effectively be rid of DRM, however, it seems that it has been banned by the developer once again (this is what caused previous problems with this title).
We have contacted them regarding this issue already and are working on a solution as we do realise that having DRMed games is simply not an option.
That is why I'd suggest that if you run the game, you run it offline or adding it to your firewall to block it froma calling home (it should work without the key that way) - we know that it's a very WIP solution and hope for it to be as temporary as possible, and we'll let you know once the issue is resolved and the game is DRM-free once more.
Your statement indicates you knew beforehand about this and yet still allowed it in your catalog. A game that calls home whenever it finds an open internet connection is DRM'ed flat on. Blocking the game with a firewall is a workaround but doesn't remove the fact that the game has an active DRM in it.
What about those who don't use a firewall? Back when I used Windows I never used a firewall, never needed one myself and unplugging my connection for a game that's supposed to be DRM-Free in the first place is wrong.
With that said I understand some games don't work without a present serial key installed, I'm aware that such keys are installed by the installer in many other games here on GoG but unlike this one they don't call home which makes them worth of the DRM-Free title.
Thanks for working with the devs with such an issue and please, be careful what you sell, news run like wildfire these days on the internet and I'd hate to see GoG's good name put in bad light.
