If obviously not exactly the same or it would work ;-)

If you can reproduce this error against one of the example databases
(for example employee.gdb) then perhaps you can send (privately) the
source for the demo project so I can see what is wrong.

If you cannot reproduce the problem on an example database it may be
time to look at your database structure - check that your primary key
is defined as given in KeyLinks etc.
