HUGE Problem

Hi guys, I'm sure this is not the right section to ask this question but I'm new, so maybe its right.
I tried to make my own Game with the Pokemon-Starterkit for RPG-Maker XP.
But if I start the game to test it, the following text appears:

---------------------------
Pokemon Essentials
---------------------------

I hope you can help me...
