I've downloaded the FB Replicator and tryed it on my database. When I want to add it as a souce database  I enter path to the DB user pass and click save, but it gives me the following error:

ISC ERROR CODE: 335544323

ERROR MESSAGE:

file is not a valid database

The problem is that it is ;). After 4-5 attampts it gives me another error with something about a closed DataSet. What should I do? Is there any documentation about it? I googled the error and ... nothing.

Thank you
