How to control importet character?

okay, maybe this can help to understand my problem, i noticed when i hit possess while simulating/playing it gets into a fixed camera, but its still not the mesh i inserted but just from the position i started the sim and when i to this my camera is falling down from the world and i cant get her to stop falling, i tried it again without possessing and noticed that there is a little system with the three axis z,x,y falling and i dont know how to fix it :confused:
