I just bought Civ 3 gold, all of the requirements fit, i successively loaded the first disk, but when i switch to the second disk it claims there is a parameter error:

Component: PTW_Program_Files
File Group: Modified Art and Units [All PTW]
File: E:\data3.cab
Error: The Parameter is Incorrect

pressing 'ok' it then ejects the disk and goes to a blue screen saying:

Error Reading disk
Insert Disk into drive E:
If disk is alredy in drive E: it may need cleaning

I have cleaned the disk and restarted but the same error occurred,
HELP!!!
