DevArt ODBC Driver for NetSuite 3.00.01 Reports 'SuiteTalk endpoint version 2016_2 is no longer supported'

We had the ODBC connection working fine and returning data. Now the connection is returning the error:

> SuiteTalk endpoint version 2016_2 is no longer supported

A few weeks ago, we seemed to resolve the issue by upgrading the driver version to it's current version (3.01) but now we are getting the same error.

We are using API version 1 and Token-Based authentication (which was previously working).

Can anyone shed light on why our connection is now not working?
