CnM Touchpad 7 Question

Hi

I just bought a CnM Touchpad 7. I recently downloaded FM13 for this Tablet, I installed the game and the data then when it loads if shows the 2 parts of the game at the start then the screen goes blank, I can see a little line at the top of the screen but not the full game.

The screen is 800x400 is this enough to run it? I would of bought another tablet if I hadn't of known the spec was the correct one to play this game.

Any advice? thanks.
