Thanks for the reply. I had downloaded the keys a few times with the same result.
However I managed to locate a copy of the v6 software. I uninstalled v8 and installed v6, however the registration codes still wouldn't work.
Then uninstalled v6 again and went into the registry and exported and saved a copy of the registry. I then deleted any reference to DVDFab and restarted the computer.
Installled v6 and the registration codes I had worked. I then installed v8 and it is now registered , I'm a happy camper as the problem I had is now resolved.:bigsmile:
