Hey, I just got brothers in arms and just before starting a new game fiddled with the graphics settings a bit (i just got a new graphics card and wanted to see what it could do). I changed the resolution and now all it says is "This video mode cannot be shown" or something in the middle of a black screen.

Is there any way of reverting to the origional settings without going into the game and going on the options menu (i cant do that because it only shows black, although it does play sounds and I can still click on stuff, but i cant see). Or is there any other way of getting the picture back?

Thanks a lot everyone.

Ps. I'm a complete rookie at computers so please explain stuff as if you are talking to a moron.
