singer data

[Dufgolfer]

I upgraded to 5.04 last thursday and rebuilt my song database and checked some songs etc. and everything seemed ok. I did a show Sunday evening and my singers were all there but there song history was gone. Several of them had one song listed but most had none. Is there any way I can retrieve this info? I checked the windows upgrade list prior to downloading but found nothing new that I needed to do.
