Accidently set game res too high

Yes, I'm a dumbass. And not very computer literate either. Anyway, I run with a Windows XP home edition and, while playing City of Villians, decided it would be a great idea to see how "good" a resolution I could get. I don't remember exactly what resolution I set it at, but I set it above the 1240x780 mark. Now, when I try to run the game, the screen goes black and I get a "Input not supported" message. Could I get a little help? I have banks to rob!

Edit--by the way, I also set me refresh rate up to 75 in the game (not on my computer). Bad idea now, I know,

 

If you're using an LCD, leave the refresh rate alone. On a CRT, the higher the better. I dont know if this will work or if its even possible but maybe create a profile in your video card's control panel and force a resolution lower than what messed it up? doubt its possible but maybe. only other thing i could see that would fix it is to reinstall it but thats a real pain seeing as you'd have to reinstall all the patches....

 

Start up City of Villains in safe Mode. You'll see the check box next to the Agree button on the EULA window. It'll reset the game to defaults, and you can make whatever graphics adjustments you want from there

 

Thanks!
