Getting external data from ODBC error 3423

[Jimi_83]

With Access 2003, I am trying to import data from Simply Accounting. When I
try to open the data source under Machine Data Source, I get the following
Error:

You cannot use ODBC to import from, export to, or link an external Microsfot
Jet or ISAM database table to your database (Error 3423)

Simply Accounting uses ODBC.

What am I doing wrong and wow do I get around this problem?

Thanks.
