The game only works for me right after I install it. If I install it and quit, when I go to reboot the game, it will not start. The hour glass just blinks when I double click the icon to run the game. Any ideas?

I have exactly the same problem. Suggestions, anyone?

I noticed on my computer that the game will start for me if it is the only running application.

If you are on Vista or Windows 7, you might try installing to a folder other than "Program Files (x86)"

Has anyone tried running it via the start menu?

I know that worked for me!
