Can't backup my music with Nero anymore?

[Eyeball Kid]

My neighbour just got broken into and all his cds stolen, so I want to make backups of all mine. I tried using Nero by creating an image file and burning back to cd, but it keeps telling me it's unable to because the cd was copyrighted. I'm pretty sure I did this before with an older version of Nero - has something changed in the newer versions of Nero?
