[Gretl-users] ODBC dsn=.... error

I recently upgraded to the latest Gretl release to take advantage of the join functionality for .gdt tables. Unfortunately now my "Open dsn=" statements produce an error. The statements worked previously - and when I reinstall the previous version of Gretl - they still work. However, when I install the latest release from April 2015 the statement produces the error. The statement producing the error is: "open dsn=GretlPort --odbc #This is the (Gretl Port Engine.accdb) The error produced is: "You must specify a DSN using 'dsn=...'" I have reviewed all of the documentation and any relevant information from the users list. Any assistance with this issue would be gratefully appreciated. Thank You in advance.
