Hey Buster. When the app turns off and that error pops up it usually means that there was an issue with the memory, e.g. The app's memory demand exceeds what the platform that runs it can offer atm; Or there was a general memory issue of another kind.

Did this happen when you tried to enter an F.A. match. You do say that it happens on that specific account at the first week of the F.A. competition.
