Copying CD tracks.

I have, for some time, been successfully using the supplied Roxio programme in my laptop for compiling CDs of music tracks for the music evenings I put on at this retirement lodge.
Recently, however, I have been unable to do so, for although, apparently, it goes through the business of burning, the CD comes out blank. I'm still using the same blank discs (CD-R).
Thinking that perhap the Roxio programme had developed a fault, I then tried using Windows Media Player, but with the same result.
I am still able to transfer files and photographs on to a disc.
Any suggestions?
