So I've downloaded the latest version of Pokemon Essentials v16. I open it up and just tried to do a play test with what was there. it loads to the very first screen (New game, Continue game. etc) and crashes with this error

I've searched everywhere and can't find a solution that works,
yes i have tried reinstalling Pokemon essentials.
And i have tried installing the pokemon pack v1

Does the player have any Pokemon of which don't have an icon? I know for a fact that can cause the game to crash at the start screen.
