MPVI not working on '14 Mustang GT

Hello,
Working on a '14 Mustang GT that I have tuned a bunch in the past. Trying to read out or load tune it giving me an error saying I can't use the MPVI I've been using for years to tune this car and must use the MPIV2, which I don't own. Using editor version 4.0.12. What's the issue here? Please don't tell me I have to upgrade to a MPVI2 to tune cars I've previously tuned and already paid for credits.

Thanks,
Paul

Please open a support ticket, for reference there is no error(to my knowledge) that says "I can't use the MPVI I've been using for years to tune this car and must use the MPVI2".
