Some kma files cannot be added to database
 

I hope someone can help me. I copied over a folder of karaoke songs from a harddrive that was dying. I have managed to add the new folder and rebuild the database. Most songs will show up when searched for, however, there are about 12 kma files that will not show up. I have tried rebuilding it several times but I am unable to get them to add. I can access them with the k-oke button and they play fine. Any ideas what could be happening? Any help would be apprec:?:?
