Answers to your questions...
My PC was completely wiped clean and windows etc re-loaded.
My OS is XP professional edition
erm not quite sure what you mean by your third question..
When i put the disc in question in to my machine, it seems to be trying to read the data on there, but then stops.
I have used the drive to read other discs without a problem so I know it isn't the CDrom drive at fault.
Thanks
