Game shutdown, after battle ended.

Okay So I just updated to the newest format after over a year since the last time I updated, After my first battle since coming back, where the closing page usually is (where you can rate the other players and review the battle) the game just closes out. I still had the program showing in my task manager, but couldn't open it until I ended task and reopened it.

I am running a 64 bit, Windows 10 HP, 8GB RAM, 3.4GHz-i7 CPU.
