Hi all! I have a serious problem that does not allow me to virtually play: every time I load the game (I own the version 2008 for Steam), the options screen becomes black and only pressing ALT I can restore it. At that point, however, pressing the left mouse button everything returns to be black and so I'm forced to press two keys repeatedly to proceed!

I have a G100 nVidia graphic card, using Windows 7 with 3 GB of RAM. Could someone help me? Thanks in advance!
