FlexTV.bundle FlexTv.bundle fails to load

It seems that the plugin is not compatible with the latest plex build.

Plex is running perfectly from docker image https://hub.docker.com/r/linuxserver/plex/

I get ImportError: No module named _ctypes

I tried installing FlexTv.bundle using both methods ( git and webtools ) with same results.
