Can anyone help with this problem?

I cannot open client dataset. When I set the dataset.active = True I receive the following error message:

"Prepare SQL statement failed. Dynamic SQL Error SQL error code = -204 Table unknown MYTABLE At line 1, column 15."

I have converted an Access mdb to Firebird (ver 2.1.3.18185). With IBExpert I can see all the tables and data correctly.

In a Delphi form I am using a TADOConnection and a TADOTable component. The connection component is 'connected' and in the table component I choose the MYTABLE table fronm the drop-down list. When I try to set the TADOTable.Active property to true I receive the error.
