Why can't SonicStage and OpenMG Jukebox be used after System Restore or Registry Checker is performed?

Err Msg: Invalid OpenMG contents specified

Note: Once the error message appears, there is no other way to restore back to the original state.

Always back up the SonicStage or OpenMG Jukebox database using Backup Tools before performing any System Restore. When restoring the backup database, always restore to its original location after performing System Restore.
