I can't get onto or create a new world

[SkyAlpha0711]

I need help when uploading Attack Of The B-Team. When I go on, it loads up and all until I try to create a new world or get onto one already made. It comes up with a screen explaining what is happening and then it says 

|Return To Title Screen| or |Quit Game|

If you click the first one, you still cannot go onto a world or create a new one. Please help me: I want to try out AOTBT and see how it works

 

~Thanks
