Just as a feed back.
I only get the error when I try to access the DB on Firebird Win 64 Bit server (Tried with 2.1x and 2.5x) and when the original DB came from a server with Firebird Win 32 Bit (2.0x, 2.1x). But it happens only in about 50% of the cases.

When I install a 32Bit version I can access the DB 100%.

BTW thanks for the everybody on the support group. I learn a lot by reading your questions and answers.
