That's not a very descriptive assessment of the problem. "Can't open the disc"....there can be 100 reasons for that. Without knowing exactly what error you're getting, it's impossible to say.

Sorry was just reading the message it gave me:

The ahem "key" in that message is the volume key unknown part. That should clue you in to look at the filename and compare it to the ones that have already been posted as not working.

Thanks, I'm no expert at this but figured you guessed that already.

Can confirm that Prey4K US from Amazon rips.

Yup it's working now.
