Hello. I have a desktop machine and it is been installed with Windows 7 professional edition. I have installed Bad Company 2 game application to the system. The problem is that the game will not work with SLI mode with V196.21 nor V196.34 Beta for my Geforce GTX280 graphic card. I get an error message that there is no disc in the drive. Please in tall a disc in Drive/Device/Harddisc2/DR2. Please help me out for the same. It would be a great help. Thank you.
