Open your account, and in the main screen, where you define the access code, etc., there is also a button which lets you configure the M1XEP (you probably know this). Sending changes to the M1XEP in that screen should force a reboot. If the button is grayed out, then change a value, and change it back to the original value to enable it. I am not sure if it reboots for all types of changes, but worth a shot.
