Hoster not reading CDGs - Required updating Hoster for Win7

[FRadspinner]

I made all the Windows7 changes and installed Hoster. I have a Optiarc DVD+RW AD-7747H 100A Drive. When I open Hoster and attempt to import karaoke songs from the CDG disk, Windows Media player opens it instead. So I close Windows Media Player and click on "Search Online Database" then I get this message from Hoster: CD/DVD drive not ready. Please insert a disk and try again. It will not load the disk. The CD drive is working as it reads music disks. In the Windows7 change I did do Change #3 - Disable CDRom Auto Play Option. Any ideas on why it is not working?
