Help! can't copy downloaded music to cd

I purchased a bunch of songs on and I cannot seem to copy my files to my cd. Can someone help me out here? I have tried useing Nero and it say’s " files could not be added because the file formats are not supported". When I try using cd extractor the message “error reading.wma”.
Please help I need to resolve this very quickly. I checked the frequently asked questions sections and it mentions being able to burn cds.

I just noticed a specific section for audio, sorry of the other thread.

Wal-Mart’s WMA files are “DRM enabled”. Windows Media Player should be able to burn those songs to CD. If it can’t, I don’t think anything can.
