So what should i do? install patches? contact support?
If you are running a stock retail copy, then yes, definitely update the game; this can be done using Impulse (sign in with your forum account, click the (?) in the corner to access the registration screen where you can add the game to your account, then go to the My Games page where you can update it).
If the game still has issues after updating to the latest version, please contact [email protected].
