Need help with WSB2K2!!!

[dukes88]

I have had all the files for wsb2k2 for a couple of days now, but I can't seem to UnRar the files. I get a CRC error(file is broken) error everytime I try. The first time I tried I got an error with the 24th file, so I d/l it again and tried but started to get this CRC error. It makes it to the 20th file and then runs right out to 100% on the 20th file and then gives me the error. I tried d/l all the files again from 20-24 but I get the same error. Does anyone have any ideas on how to fix this or what is wrong without having to d/l the entire game again? Also, I did check all the names of the files and the second time I got the 20-24 files I d/l them from another person. Thanks..
