Thank you very much! 
Heya I'm newly back from a 2 year break to check out Going Rogue. Sadly when I play I get a crash about 20 minutes in that says my Nvidia OpenGL drivers have had an error. I don't see a tech forum so I hope this is the right place to ask for help. I'm running Windows 7 32-bit.
