"calling CDS: failed, restart required" ?

HELP!
I installed Doom 3 and ran it a few times, and it worked fine. Then I changed it from fullscreen to windowed. It said i had to restart the game, so i did. It ran fine for the time i played it windowed. Then i changed it back to fullscreen and had to restart again, only THIS time, this error came up saying “error starting opengl”. This followed:

any ideas? Help would be WONDERFUL!!! I tried re-installing it, but that didn’t seem to help.

Also, I did download this cpu “boosting” program called Hare, but i uninstalled it after this happened, and i still get the error.

ALSO, Unreal Tourny 2k4 quit working, saying there was a runtime error.

Help pleeeeeeease!!!

yea…um…nevermind, this program called Sysmetrix was running…i made it stop running…and now it works…man, i feel PRETTY stupid.

JEEZ, and i spent ALL THAT FREAKIN TIME typing up this LONG thread…welp, reply if you must comment. But, why would sysmetrix make it not work???
