Same problem. Again.
The following is not an issue:
It was correct in the file and did not need to be changed. Bandwidth is not an issue, it is unlimited. Also, the sessiontest was fine. The clients' website is hosted on BlueHost.
The only difference this time...I re-installed (using 1.0.1) on a local host.
Installation was fine.
Based on the Connection.php I am using the correct ID & Password.
