You top man! What a school boy error. I had unzipped them into another folder and then copied them across, I copied the folder above as well, its working fine. And it was the same muppetry that stopped Targa working! All sorted. Really appreciate your help. A question for you, if I were looking for a more modern sim with better graphics and a similar selection of historic cars to race but also good physics, what would you recommend? I am not going to stop playing these as I had forgotten just how good they are but I have a fairly potent PC and could run something a bit more modern to try.
