Nero is driving me mad

I had a problem with nero but a wonderful lady on this forum helped me out and it is working. But, okay I have a pentium 2 333 128 meg of ram 64 meg radion video card. I have a IDE 50x cd rom and a MSI 40x CD_RW. Now my problem is small, I loaded in 200 megs of mp3 (winamp media) and started to burn. I am using memorex cdr platinum 700 meg 80 min cd-rs. When I start to burn these files everthing is going fine then it will say (Could not perform fixation, Session fixation error. I have had the rewriteable cd for about two weeks. And Nero did an amazing job on my other mp3s and my music videos plus a few files. Then all of a sudden it didnt work no more. Kind of broke this old gentlemans heart didn't have my new toy to play with. I would really appricate if someone could help me out.

Hi... check this link out from the Nero help pages...

http://www.nero.com/en/content/helptool/530.htm

from there are some other links to lists of possible reasons for getting that error message. My first inclination would be that it's the CD itself and to try another one but check out the other possibilities too.
