Query: CD Not Playable

Thanks to the RIAA and the VERY restrictive "anti- piracy" measures used on this CD, I was forced to return the CD to the store (For store credit, as the CD was opened....) due to the CD not being playable on my computer, or mp3 player (the reason i purchased the CD, and which are both legal uses of the CD. The anti-"piracy" measures are very extreme on this CD. I use "piracy" in quotes as I was not even allowed to use the CD legally.
