AFAIK this is a known issue if you've upgraded a 32-bit mediadatabse 
from an old networker to a newer 64-bit nw and mediadb.

I don't think there's any other way around it than making a complete new 
64 bit backup server and then moving the data to it. That is use scanner 
to populate the new media db (yes I know).
