I found out the problem, something is messed up inside maya 2013 settings.
I made backup of org in mydocuments and cheched with fresh, it works..
I just need to find fbx or other bad settings for this plugin in in settings and it will be fine.
Thanks dave you always help me !
---------------------------------
I deleted everything in maya documents except projects and shelf settings, that fixed problem.
Maybe it was plug-in settings, something corrupted inside.
