Matshita DVD RAM UJ-850S ATA Device not working

I have a sony Vaio laptop (vgn-n220E) Recently my driver failed for my dvd drive, When I first got the laptop I was able to install a few things and burn some CDs.

Now about a month later, I can't read or write CDs or DVDs.

My device manager for the CD/DVD ROM drives sais

"Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available."

The check for solutions button does nothing.

I uninstalled the driver and restarted my computer and it reinstalled the same one which once again doesnt work.

I do a driver update search and vista is telling me the driver is up to date.

I have checked sony updates with no such updates for CD/DVD rom drives.

I am clueless on where to check or how to repair this "corrupted" driver.
