Screen blank when playing songs

[Ernie]

I downloaded my traveling disc on Microstudio. I then opened Keyrite and changed the keys on all. I then recorded a blank disc and installed the newly recorded disc back onto Microstudio. When I play a song, the music plays, but the screen that opens just stays blank. My traveling disc works, but not the ones I changed with Keyrite. I have XP, all updates, Hoster 4.06. I did a name change when I used Keyrite, so I know I have the right ones. Any ideas???

Thanks,
Ernie
