Hoster not reading discs

[Azkaraoke4]

Hi All, I'm new to hoster and just got it a few days ago. It has been working great and I have got a lot of info from here, Thanks everyone. However I have hit a snag. I have imported all my dk's all my sd's all my sound choice and I was on some nutech disks. I imported 2009, it's a christmas one. It showed 24 tracks but only had song and artist listed for the first 12 songs. So I just impoted the fir 12. The problem is now hoster will not read any disks. I tried 2010, 2011, 2012 and then I rebooted and tried them again. Nope nothing. Then I rebooted again and tried to do a chartbuster disk and had no luck. I can play kma files and do the normal karaoke stuff but hoster will not read to import any disks. Can someone help? I am running what I believe is the latest hoster seeing that I bought it less than a week ago and I have p4 2.8ghz 1gig ram 60 gig hd xp prof and the plextor 708a.
Audigy 2, radeon 9000 128mg. And yes i did slow down the acceleration on the sound card

Thanks in advance.
