Zbrush to Maya GoZ not working

Dear All,
I wish to use GoZ from maya to zbrush to export my scene (i assemble it in maya, not in zbrush due to xgen as I told asked another question). When hitting the GoZ button, however, maya starts then freezes. From maya to zbrush it works just fine.
I use maya 2016 and zbrush 4r7, on windows 8.1 pro, all updates installed, visual c++ executable somethings installed, on amd radeon hd 8730m 14.11.2 beta catalyst driver. ram is 8gb, 4 cores of i5 i have, the system req should not be a problem.
any ideas?
thanks in advance.

Make sure you have the latest ZBrush patch installed. Your ZBrush interface should say ZBrush 4R7 P3 at the top left corner. There was an issue with GoZ to Maya in the early release but it was resolved for P3.
