I had a problem with the heroes when I was playing, but now the game won't launch. Help!

Basically, the problem is that I have the latest drivers installed... when I launch the game by clicking on the shortcut, it doesn't start, but it does load the system in the Task Manager... I have a 7600GS graphics card, 1.5 GB of RAM, and a 2.4 GHz processor... the computer should be able to run the game without any problems... so, what do you suggest I do?:confused:
