Vista Issues?

[Cruz Control]

Good Morning Everyone
Well I finally got my Hoster installed on my laptop with the new Vista Ultimate. Just an hour before my show last night. BTW Thanks to Support For getting back to me (: here is what I ran into last night…….. when playing a kma and I go to import a customers cdg for their turn the video would freeze or the audio would freeze or both during the writing process. So after restarting the customers song after it got buggered up… I tried it again…… this time the I received a message from Vista saying that the video driver has stopped responding and the Hoster program will be shut down. Ok…. So now I’m thinking this isn’t good….. I Restart Hoster and continue on with my show after some time I get brave and try to import a cdg this is after I have now set my audio drop out to “c” same thing as far as the pause or stop of video which when returns in all cases is now out of sync………
I would really like to get this fixed before my show tonight……. Any one with any Ideas?
