I think you need to get a fresh copy of the original database file from your customer, taken when the database is certainly off-line.

Better still, ask the customer to shut down both the database and the FB server and make the copy for you, on site.
Then, when you have a *true* copy on your own machine, make another copy locally to work with and *store the fresh copy safely* somewhere. Then, each time you try something different, begin again with a new copy of the "safe" copy.
Do the steps in the right order, as described in the Analyse and Repair procedure.
If that doesn't work out, then download the free IBFirstAid Diagnostician tool from www.ib-aid.com. Work with *another fresh copy* of the database. Doing things in the right order is essential for this tool, as well, so READ THE DOC. The free version of this tool does not repair a database - it is for diagnosis only.

>Thank you for your answer Helen.It seems likely that *your copy* is corrupt, probably caused by your earlier attempt to perform gfix -mend without doing the preceding validation steps. It is also possible that you had a "bad" copy originally because the database file was copied while the database was on-line.
