First instances hung on 59% and crashed, next I fully loaded and got one frame from the world before a crash, and the rest fully loaded with no glimpse at the game. 10 attempts, crash reports below:

Attempted to use the 35.1.5 version of Forge at the request of @GL33P-0R4NG3 , first and third crash were 100% loads followed by a crash, the second hung at 6% and I had to use task manager to crash it. Two new crash reports below (second crash was forced):
