On my Windows 7 64 bit PC, firebird is currently installed.

I used to open a database file using isql command in previous firebird version 2.1.3. It works well.

However, the latest 2.5.1 version gives me a weird HY000 error.

file C:\TEMP\DATABASES\FBPORTFOLIO.GDB is not a valid database

Please download the database file from

Please help me to open this database file using 2.5.1.
