Dale,
I had something simular. In my case we did had uninstalled and installed SMVI again. Next morning we had trouble with the snapshots. There was a problem with renaming the snapshot to most recent because it already existed. Apparently the SMVI did not recognise the previous install had already made snapshots. Maybe this KB article from the Now website can help.

I must say, I was glad I had my engineer from the reseller at hand.
I hope this helps you.
Regards,
Dirk-Pieter
