Not showing Songs

[S. Parks]

OK, never had this one happen before. Booted up the computer, opened up Hoster with a new disc to import in my USB Plextor 48-24-48 drive. Normally as soon as I click on a disc brand, such as Chartbuster Professional Country, in this case, the tray will close and the drive will read the tracks and show how many are there, and then I'll select the specific disc number. We now, the tray didn't close automatically, like it normally would. When I checked the detect drives, Hoster showed the drive and said yes in both columns, so I know Hoster detects the drive. But still it won't read the disc, even when I click on the read tracks tab. Is this a Hoster thing, a Driver thing or what. I tried reinstalling Hoster, but that didn't fix anything. Any suggestions would be greatly appreciated.
