Can't load new firmware on Pixhawk controller

Mission Planner 1.3.56.4 build 1.3.6761.35685
Original Pixhawk

Can connect to pixhawk with no issues but when trying to load new firmware get no board detected.

Select load firmware and unplug unit and then plug back in after pressing OK and get error.

Cant detect you Board version. Please check your cabling.

this is a dll issue with the beta MP.

please do an update to latest beta.
then do the update again. as the seconds update should remove the bad dll

Mission Planner would not detect any updates so went to the help screen and click on Check for Beta Updates. That fixed the problem.
