Titanium Install Error. Could really use a fix here!

[Belwri]

I can't install on laptop or main PC. Getting this error at same point on same file. Discs only ever used once. How could they be faulty? Any one got a fix for this?

I get a pop-up that says: Component Transfer Error-Component: Titanium-File Group:EQ Files-File: D:\data3.cab-Error: Data Error (cyclic redundancy check).

Happens at same point every time but discs only ever used once.

When I either close or click "ok" on this pop-up the installation closes entirely. Could really use some help here. If it's techy please be clear - aint really my area. Thanks.
