Nero Express Essentials problem

OK, the problem is that yesterday and today I was sorting out my music files in Windows Media Player by attaching the right cover art to every song as well as the additional info.
Than, when I tried to burn out the CD as mp3 or normal audio CD, I get this message:
Example:
“It may be possible, that the files can be added, if a dedicated plug-in is installed.
C:\Documents and Settings\korisnik\My Documents\My Music\Michael Cretu\Michael Cretu – The Invisible Man (1985)\01 Michael Cretu – Samurai.mp3”
The interesting thing is that I was able to burn that same album/song before updating the data.
Now, Nero doesn’t allow me to do that, or in the best case, when I put the album with 10 song, he puts 3 or so.
What should I do now?!?!?
PLEASE HELP!
