Hey I recently purchased the new DLC for Sins and am having issues getting it to run. I followed some of the troubleshooting steps on the official pinned thread including updating my drivers.
I can get the game to run in windowed mode by manually editing the settings file and then switching it back to full screen in game it runs fine, but it still crashes when set to launch full screen mode which I thought was really odd.
I'd also like to add that while I understand getting things to work on all of the multitude of possible setups that occurs with PC gaming, it's pretty disappointing that Stardock managed to break a game that was functioning just fine, and still hasn't fixed it yet. Maybe I'm just too used to everything "just working" on Steam, unlike back in the day when troubleshooting was just part of the process, or maybe I just expect more from games these days, but take that for what it's worth.
