It sound to me as though you did things in a slightly different order to
this: installed FB2, created the database (with IBExpert, Charlie's
Chocolate Factory or whatever), uninstalled Fb2 and then installed FB 1.5.

Try Ann's tip - install Fb 2 somewhere, replace Fb 2's gbak program with Fb
1.5's gbak and try to use Fb 1.5's gbak to back up the Fb 2 database. If
it works, you would then be able to restore that gbak file back as an ODS10
database under Fb 1.5.
