I installed the 2012 mod and everything was working fine. I imported the dat files into MVPEdit and made some roster changes and exported it back. I checked for errors and none were found. The game loads fine, but crashes when you click go to play a game. I checked all the rosters and found a null spot in the Frisco RoughRiders lineup for LHP W/O DH. I also imported some players and rosters are fine in MVPEdit. How do I fix the Null problem?
