Game won't start cause i set screen resolution too high?

As the title reads, I set my screen resolution to 1600x1200. I have a 20" Acer LCD monitor. Anyways... I set it to that resolution and the game locks up. So I ctrl,alt,delete my way out and when I try to run it again, it says "preparing game" (as usual) then my screen flickers and goes black as if it's loading the game (as usual) but the game doesn't load. It just sends me back to where I last was before I clicked "play". I'm guessing that resolution screwed it up somehow but I don't know how to change it back without deleting the game and starting over... Any suggestions? Please don't click out of here if you have an idea of what I can do. Thank you!

I think running the game with the -autoconfig parameter should set everything to default. If not you can set the width and height of the window with the -w and -h parameters.

How do I go about changing the parameters?

Right click on the game in your library, click on Properties, then click on Set Launch Options and put -autoconfig .. then try to launch the game again, as soon as it's fixed, make sure to remove the autoconfig option the next time you run the game.

Thanks guys. That did it. Learn somethin new everyday...
