Here's a new developer release, it has many fixes related to live playback which should reduce the Temporary Loss Of Signal (TLOS #3) errors people have been getting.  Please try it out and let us know your feedback, by channel chat in My Joost or email (support@joost.com).

Download preview release 3 for Windows

Update - Unfortunately Preview Release 3 was found to have a nasty bug, check back later for a new release.

Thanks!
