Battlefield 2142 Resolution

I installed Battliefield last night, and was ajusting the video settings, and set a resoluion outside of what my monitor supports......when i launch the game, the screen automatically goes blank "outside of range". Is there anyway i can set the game to run at a low resolution so i can get in and change it back to a supported format? I tried one suggestion that involved added +svx 1280 +svz 800 to the target line, but it didnt seem to work. Im using Vista Ultimate,

Right now im running an old 17" untill i can afford the Dell 2407 8)
the native is 1280x1024. When i type that in the target line, vista gives me a message that says " i need administrative privileges" which i have, and i set Battlefield to run as an ADMIN proccess....after i hit ok, it appers to stick, but when i launch, i get the "out of range" right away. If i uninstall, and try to re-install; do u think ill have activation issue???

No, i didnt download the patch....do u think that could help? This would be the 3rd time ive activated the game......1st on XP, then again on Vista. I just dont want to get denied......
