Need help with exporting FBX for motion builder

I need to export armature and animation that I made from blender to motion builder. I tried to use FBX but when I open the file inside motion builder armature looks like detached small orbs instead of connected sticks, pretty sure that its broken. Other FBX files looks fine, but ones I made are all like this.
I saw couple people doing it so it should be possible, like here for example: https://www.youtube.com/watch?v=rPLdn0nf5Kw
I tried exporting using his setting but my result was still the same. What am I missing? Maybe there is a custom FBX export plugin that works better?
