Drawing crash

The maps look great they look pretty up to date. however I got this app because I was looking for a program that would allow me to draw on a map and save my drawings I wanted to take a portion of the map and break it into territories and give it out to different people unfortunately after spending a couple hours drawing on the map it crashed and I lost all of my lines currently it wont let me drawn at all it crashes as soon as i hit the draw icon.
