XBMC for windows v12 not able to browser uPnP server folder

I recently upgrade my XBMC for windows from v11 to V12, when try to add video/audio/picture, I was able to find the uPnP server(NAS from Western digits), but not able to browser the content in the folder, on error shows up.
Downgrade to v11, everything works fine.

Any idea what went wrong?

I did the upgrade/downgrade by install the software to same directory.
