Then GOG should not sell a game that is faulty and not working on new systems (if its true what H2IWclassic said).
They should not release it then as Good Old Game but cannot run on new systems.
I have this problem as well and it frustrates and irritates the crap out of me if my missions keep on failing about 10min to 15min in the mission, i have not even finished building and then getting that message.
They should either fix this or remove game from shop and not sell it since it has a major bug then.
Just my opinion but you cannot play nor enjoy a game like that.
Have you contacted their tech support?
Hi H2IWclassic, yes i did contact support, this would be my 3rd game i report and ask for help from support and this would be my 3rd game where it was not resolved.
I will give GOG credit for at least replying to my initial (first) support calls but they do not resolve it at all. The 2 other games still not resolved but GOG did at least reply to me to try and help with basic answers.
I recon this game would be the 3rd and will not be resolved as well.
I have bought almost their whole catalogue of games here but have only played (tested) like 25 of them so far.
I just wish the support could be a bit better, you get the initial reply and basic help but then the support just fade away even when you reply and say it still does not work after you did what they said and then BOOM, no replies after that. It feels like support just ignore you and wishes you stay away and leave the problem. This is my opinion with the support i received. Maybe other people got better support but this is how i was helped. I can also understand that these are old game and you could have problems on new systems but when users report or log calls then i would at least expect them to test better and list the problems received so that customers could make a better judgement call if they still want to buy the game.
