Hey all,
I frequently encounter this problem (runnnig on Mac OS).
I usually make sure to SAVE BEFORE trying to solve the camera. A lot of strange things can happen during the solving stage, so always be sure to save.
As far as getting stuck at 66%, what I always do is double check my tracking points. There's an issue with something, so if you're getting that error, it's probably an indication that something is throwing matchmover off.
Best,

I had the same problem when using TGA sequence.
So I tried jpeg sequence and lowered the resolution. That helped.
It's still pretty annoying that the selectable image formats do not work.
