Couldn't Hot Route or Audible. Any1 Havin This Prob?

For some reason during 2 online games vs 2 MS members, right in the middle of the game, my audibles and hot routes would stop corresponding. My QB would be yelling out crap, but nothing would change. It was as if I was faking my changes to the play. It didn't cause me the 1st game, but in the 2nd game while I was tryin to make a comeback in the 4th quarter, I wasn't able to at least attempt to do so because I couldn't change my plays.
