Mixamo imported character places shoulders too high

[#1]

i made a character on makehuman and uploaded to mixamo (via blender to do some poly reduction) and it works except for a strange effect as seen on the image 

the makehuman looks fine, shoulders arch down a bit but in mixamo she looks like mr gumby from python

any ideas how to fix? there is no shoulder control on the mixamo rigging tool. thanks
