Hi all, New to the forums. Playing call of duty united offensive. Had to do a system restore after a hacktool rootkit virus struck me. Quarantined and deleted it. Upon reinstalling cod/uo, I get error 1628 most of the time. Im using windows xp home. Cod/uo hangs at about 99% and wont install. Ive done everything over and over, with drivers updating rolling back, system restore from symantec boot cd. Same problem. Quake 4 installed but wont load. Regular COD loaded and installed. Far cry installed plays fine. using nvidias 78.01 drivers. had blue screen errors nv4_disp. Rolled back to 78.01 so far so good. This is baffling to me. But Im sure there is a fix. Help me for the love of GOD!!! Somebody help me!!! Im cracking up!!!! Thanks.
