Not able to burn data or audio using Windows XP Wizard and External CD-RW

Hello,

  Up until recently I was able to use the Cd-burning Wizard through Windows XP to burn both audio and data on Cds using an external Cd-rw drive; however, the Wizard now fails to do so.  I am able to burn audio using a trial version of the program MusicMatch that came with my computer successfully, but not with the program, Nero, that came with the burner.  From what I have gathered on Microsoft.com in the Windows Media webpage, the problem may have occured because of the installation of Service Pack 2.  I would like to continue using the Cd-Burning Wizard provided through Windows Xp to burn Cds, and would appreciate any suggestions to correct my problem.  Thank you.
