DRM issues with files ripped from CD: Any way to obtain license with POP/receipt/...?

Hello all!
I bought a CD back home and had it sent to my family's house there, thinking it would come in before I had to leave for overseas. It did not, and I need the files for a project. I had my family rip the CDs to our home computer and send them to me; the problem is, they are DRM protected and I cannot play them on my computer.
I have a proof of purchase for my transaction- I have my receipt for that matter; is there any way I can obtain the licenses for the file (online or otherwise) through the use of either of those, or am I totally out of luck?
If anyone has any advice or ideas, I'd be glad to hear them.

Thank You!
