I assume it runs okay in the editor?
If it runs in the editor but not in a standalone build it usually means you have FSMs saved with old action data. E.g., a field was added or removed from an action. When you run the game in the editor you should get warnings in the Playmaker Console telling you which FSM need to be re-saved.
There are other things that can fail in a standalone build but work in the editor, but this is the most common...
