Big warning - I'm not I database expert and I haven't done this myself.

The problem is probably that the backup data is not compatible with the
the latest database version. When you installed myth it created a
new database.

A Myth database expert might know how to fix the backup files, but
I don't.

It might be possible to make this work by doing the following:
1 - uninstall Myth
2 - remove the myth database if it still exists
3 - manually create the myth database from your backup
4 - reinstall myth

I believe that the myth install is supposed to upgrade an existing
database if it finds one.
