Assuming the double backslash in file C:\\DATABASES\FBPORTFOLIO.GDB is a
typo ..

Have you read the release notes about differences in the security database
between V2.1 and V2.5? Could that be part of your problem?

Can you still access the database with FB2.1? If so, back it up with 2.1
and restore it with 2.5.

If not, you've probably got a corrupt database. Try first running gstat -h
to see if the contents of the header page are readable. If it is, try gfix
-v to identify physical corruption elsewhere. IBSurgeon has a free tool
for analyzing databases that might also help identify the problem.

Good luck,

Ann
