HelpCrossFire NA RF.rez problems

I got an error with CF NA and I uninstalled the game and i downloaded it again.
I install it back on my pc. But when he comes to RF017 he got problems.
It says:
C:\Program Files\Z8Games\CrossFire\rez\RF021.REZ

An error occurred while trying to read the source file:
The source file is corrupted.

Click Retry to try again, Ignore to skip this file (not recommended), or
Abort to cancel installation.


And when I ignore to skip the file he also has the same problem with RF018,19,20,21,22,........
Please help me :s

And sorry for my bad English

Weird , i would suggest to scan your PC for viruses and re-install again .
