Toca Race Driver image burning problem!!

[airuk01]

Hi,
I have recently purchased Toca Race Driver and i have decided to backup the discs using CloneCD so i can use Daemon Tools to play the game straight from my PC instead of changing discs all the time but when i try and install the game using the images on a vitual drive using Daemon tools, it halts half through and says that it can't install???

This is a real pain because i didnt have a problem when i used the originals? Is it because i have burnt the cd's using clone CD?

Any ideas

cheers
