Can you use the Easysoft ODBC driver for Interbase? If you have access to this odbc driver, you can import the data.
I import from Interbase to sql-server, the same can be done for Access.
There is no utility I know of that is a one-click solution that will convert all interbase tables to an Access .mdb
Doing it via odbc is not a complex solution, it should work with minimal steps.
