Says game contains a virus and wont load

The mixed reviews on steam is off-putting but the game looks interesting.

Dlc was working ok until Steam downloaded a large East India update. Now DLC showing as installed but not playable. Any ideas folks?

Have had this game for quite some time and decided to play it again. Upon opening the game I noticed that the sound (for everything) was set to zero. I changed all the settings and saved the changes. Didn't notice any changes so I exited the game and restarted it. Once again the sound was set back to zero. Anyone have any help on this issue?...

I get this message: "The application has failed to start because it's die-by-side configuration is incorrect. please see the application event log or use the commend-line sxstrace.exe tool for more details" This thing happened i think after i changed my hard disk. can you help, as i can't wait to play...
