Win2k3 Exchange 2k3 Final error: 0xe0008516 - Resources specified for snapshot do not have any valid data on them. Check if files were deleted or renamed

I have upgraded to Backup Exec 2003 and every thing went as planned, with the exception of this error.  It appears to be pointing at the Microsoft Volume Shadow Copy.  I had found and articak that said I needed to flip a switch in the node "Exchange Sever" in the registry, but I only have "Exchange".  It feels like this is one of those errors that covers a large number of errors becasue I see a lot of post but no real solution to mine.
