DVD and Cd not operating.

a while back I used this program called "Muvee" after installing it my DVD, CD and Hitachi camera drivers have been disabled I get the following message.

A driver (service) for this device has been disabled. An alternate driver may be providing this functionality. (Code 32)


So how do i get the system back up and running I tried the System Restore but it was more than 3 months ago and i can't get back to where i was.
I need my drives when tax time comes up next year and I don't want to completely reinstall my harddrive. I just have to much data on it.
