Sounds like you have upgraded from 7.3 to 7.4, and first now when you
rebooted it tried to use the new installation. The binary data files for
7.3 does not work with 7.4. To upgrade one need to dump the old and
restore into the new.
The solution is most likely to downgrade to the previous version, the one
that created those data files (7.3.x).
