Ok, im having the same problem as you guys.
The model imports facing downwards and when i hit the animate button he becomes in its right place.
I tried using the FBX importers jcl posted a couple posts back. and its still the same.
OK. now the fun part.
I tried importing the same fbx in gs 7.0 (med 6.86) and it worked fine but in a diferent way. I.e. THe model is imported and the first frame of the animation is the default position of the model.
