I had earlier imported a height map in a pretty rugged mountainous area (trying to see if there were elev limits) and it displayed the heightmap data, but acted like it imported, but the height map was uniform grey.
So i moved to a more reasonable area and tried. thats when I got error. I'll close and try again.
error msg below.
I've had no startup errors and no >32 errors with lates build.

EDIT : I closed MM and restarted. I was able to duplicate the error below in different location (NE of Novorosik.). Same error msg.
