MP 2.1 + Addon rev137 does not work for me

hi,
i use kodi v17 final and win 8.1 x64.

mp 2.1 and addon rev 137 does not work for me. i opened and configured mp2 tvserver but got no connection between tvserver and kodi. after starting/shut down kodi i was not able to start tv server configuration again. got a failure message “tv server cut not connect to ip …”. switched back to mp2 spring 16 release + addon rev137 but no connection between tv-server and kodi. mp2 spring 16 + addon rev 136 does work fine for me.
