HELP! Urgent..

[MaDe]

I have the Sims Vacation.. All of them will install fine except Vacation and Unleashed.. Superstar installs.. but during the installation of either one of those i get an error that says

Component Transfer Error

Component: Expansionshared
Filegroup: Expansionshared
File: I:\Setup\data2.cab
Error: Data error (cyclic redundancy check)

I have tried it with different drives, ive tried making an image of the disk and running it off a virtual drive all to no avail.. Any updates or something I need? Skipping Vacation and Unleashed to Superstar is like a waste of money.. Please help me!
