1.3.68 Won't Load Mission

I upgraded Mission Planner from 1.3.61 to 1.3.68 last night and now I can’t load missions onto TradHeli V3.5.2 RC1 (NovaCopter). Anyone know what might have changed and where I can download previous versions of Mission Planner?

The Heli won’t switch into Guided or Auto either. The Mode is recognized as being sent, but the Autopilot isn’t switching. No message as to why…

Ok, Found this, http://firmware.ardupilot.org/Tools/MissionPlanner/

And the Mode issue was a sloppy radio calibration. Doh!
