Well i have the same problem, but im trying to download a game off the internet. and i get about 3/4 of the way with the installation, and i keep getting errors that say

"C:\ Program
Files\Codemasters\Archlord\texture\world\low\Reference.Dat
An error occurred while trying to read the source file:

Click Retry to try again, Ignore to skip this file(NOT RECCOMMENDED), Or Abort to cancel Installaion.

Can some one help me, or tell me whats wrong?

sounds like a corrupt download. try to d/l again.
