Matshita UJ-822Da - Firmware upgrade

I have a Sony VAIO VGN-150T. Using the utility "VAIO UPGRADE" I've seen
there was a new version of the firmware of the optical drive UJ-822 and
downloaded it.
After installed the new version, my device stopped working with Audio
CDs. I works with CD-ROM, DVD but not with audio.
I couldn't find the old version to replace the new one and go back to
where I was before the upgrade.
Can somebody help me?

Firrmware is hardware issue. Go to Mashita website for help.

not XP issue.
