Vista - Problems whit Gears of War

Hi! I bought the Gears of War in PC and instalation works very well. But when I started playing then suddenly the game shut down and error massage jumped on the screen[IMG]file:///C:/Users/JJR/AppData/Local/Temp/msohtml1/01/clip_image001.gif[/IMG]. Here is that message:

So does anyone have any ideas or advices for me?

I didn't do the online version of the game but to run the single player I think you have to run the .exe file from the bin directory.

Can't remember the file name as I uninstalled it ages ago.....sorry

But, I hope this points you in the right direction.
