Well, the server is giving an error of *some* sort, but you apparently have
the wrong message file. Find the xxxxx.msg that belongs to your server
installation and rename any others, or move them out of your path. The
correct file needs to be located where the client or the server is looking
for it.
xxxxx = 'firebird' for v.1.5, 'interbase' for v.1.0

If you are on a remote client, you might be using a wrong client and
message setup.
