Agree with the above- this is unfortunately a more & more common issue.

The MHD license isn't transferable. Your PO didn't want to give you the password to their email address. Alas, you're stuck getting your own licenses, but that brings a ton of advantages, and is totally worth the $. Logging, the ability to go back to stock, or a variation of maps for your specific mods in the classic "stage" format.

Totally worth it even more for your 2013 where the ECU had to be sent off and unlocked! Most of us with earlier years could just flash, but 2013 needed to be pulled & sent off to be unlocked for a fee!

Those who think ahead set up a new email just for their 135, and then can pass the email & password to the new owner. Your PO didn't do that...
