You do not give me very much information so I must *speculate*.
I must assume that you have compiled your database application
and linked it with an old and bogus version of gdbm. The serious
bug of this library is that it reads and writes db files in *dos
text mode* instead of *dos binary mode*. All this means that you
have created broken db files using your broken application.
Later you have downloaded the repaired gdbm library and recompiled
your application. Now, your new application will read and write
all db files written in dos text mode, in dos binary mode. This fact,
probabely, originates the error message.
IMHO, there are only two possibilities:
1) Try to convert your db files from text style files into binary
style files using an utility like dtou.exe from djdev203.zip.
I have never tried this, so I do not know if this will ever work.
2) There is no way to convert the original db files from dos text
mode into dos binary mode. The db files must be recreated from
scratch.
Please note that I have been speculating. You have not given any
information to me to reproduce the difficulty. I would need at least
the timestamp of the gdbm library used to create the db files that
can no longer be read. Anyway, it is *very* likely that your db files
are lost and I would seriously suggest to download the actual gdbm
library (timestamp: 2001-08-27) and recreate your db files from
scratch.
