Install Error Need Help!

[arctik]

Well this is whats happening, I try to install Planetside starting with disc one. Everything goes good until it gets to G:/program files/sony/planetside/map02.udr and then this error message comes up:

ERROR:
Component: Planetside
File Group: Planetside files
File: D/data2.cab
Error: Data Error (Cyclic redundancy check)

Also because there is no unistaller I deleted all the planet side stuff and then tried to install the actual game discs and all (I had trial version).

All help is much appreciated, I am very stuck, I checked to make sure the disc was clean, tried installing without anti-virus components on. Still no results and the same error. Again any help is appreciated I really want to get back to playing PS.
