CDR is not obtained playable

The music'd already fallen, but I can not play the CDR to all my players. Here I would only consider this technical aspect.
That there is no CD but a CDR is delivered, the product description should be taken from. I did not expect that.
The CDR was delivered from MarketPlace dealer "Great entertainment". If I knew that other traders provide a real CD, I would try (if the return on the foreign return address too expensive and complicated is not), the return CDR and assign them to critique the dealer rather than the product.
