NFL2K1 winrar problems please help

I have tried 3 seperate complete downloads from 3 different sources (thank heavens for @Home). I have also tried 2 different rar programs (winrar and power archiver). (SHOULDA JUST BOUGHT THE DAMN THING BUT NOW I HAVE TOO MUCH INVESTED) I always get the same problem and that is.. I have crc errors with the winrar but the srv check is ok. I have tried repairing them but it says repair data not found...any clues??? I have a TDK ValeoCD (Plextor guts)
