Yep, I'm back on this thread just to tell Dart Girl.
Way to go! You did the right thing.
Since you have MicroStudio, don't hesitate to come back if you have other problems.
You may consider buying Kpro, which allow you to make custom karaoke disks that will play in any karaoke machine in addition to your computer.
Here a link with more information.
