this is a known issue the devs are currently investigating. there is a possible fix in testing at the moment. you could try attached tsreader.ax. you need to replace the one in your tvserver installation folder. but just to make sure, please replace it in both installation folders (tvserver and MP). you will also need to have the lastest vc-redist installed. see requirements and don't forget to make a backup of those files first 
feedback (and logs
) would be appreciated.
