dvd rw drive quit while importing a cdg disc

[Onepoint]

I have a new samsung laptop: Intel I7, 8gb, 64 bit with 1tb hard drive.
I have recently upgraded to Holster 5.06. I loaded the new version after I made the recommended changes for Windows 7.

I imported 21 cdg's then on 22 it quit after a few songs. It seemed my computer and or holster had locked up. I resarted my computer and can't get it to recognize any discs in the drive.

I upgraded to the latest version of hoster since and ran the test for the drive found in tools...drive checked out "good"

Not sure if this is a hoster issue or a dvd drive issue. When I checked properties of the driver it gave me a message under device status:
"device is working properly. Windows did not start related device driver. To learn more, click the driver tab and then click driver details" I did this and couldn't figure anything out. I even uninstalled the driver and restarted so it could reload. Still same stuff. I also tried to update driver but stated I had latest installed.

The dvd/cd-rom device is a Matshita dvd-ram uj8a7as.

thanks
