saved game locks up

[Holder]

I am playing Big_European_Map_2013 Got to where had all crops in And was baling my straw Then I saved game. when I come back to game I could get on & that was it. So I started another game of Big European map 2013 And got to the same spot in game and it also locked up. My FS 2013 log had these items that I don't know what means. What should I do? do I start another game or is there something I can do?
following is what log has as errors.
