NOT DUPLICATE: 'Cannot open a database created with a previous version of your application.

Hello, 

I am working on a Python script to interact with gINT data. 

I am using the pyodbc module. I can access some gINT files where others throw the following error in Python:

(0, 'DAO.Workspace', 'Cannot open a database created with a previous version of your application.', 'jeterr40.chm', 5003041, -2146825247)

However, if I go to the file location and double-click, it launches correctly in gINT. If I change the extension to .mdb or .accdb and try using Access I get an error message with the same error "Cannot open a database created ...."
I am specifying the connection string as 
        conn_str = (
             r'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=' +
              filepath +';')
Any directions/help here would be much appreciated! 
Thanks
