Unit stopped burning after installing SP2 (Toshiba SD-R5002)

[qanda]This question is published in the hardware section for the Toshiba SD-R5002. Click here to view full specs.[/qanda]I have been unable to burn CD’s or DVD’s with this burner after installing SP2 for Windows XP Home. I am sure SP2 is the culprit. I have tried burning CD’s and DVD’s on 2 different programs and it always fails. I did not have this problem before. Is there a driver update that fixes this problem? Could you direct me to the link? Thanks. I noticed the driver date is: 7/1/2001 version: 5.1.2535.0
