What versions of PlayMaker and Unity are you using?
FSM xxx: yyy: zzz should give you the GameObject : FSM : State path to help you find the error.
You can also try opening PlayMaker > Editor Windows > Editor Log.
The log entries in that window should be clickable so you can go straight to the error.
Can you copy/paste the first error in the list of errors you get when selecting one of those states? The full error in the console should have more info to let us figure out what's going on...
