PlexBMC 4.0.0 beta v4, Helper 3.4.7 - Script Failed Error

I'm running the following; (on all machines, a mix of Windows and Android)

Plex 2.4.23 PlexPass
PlexBMC v4.0.0 beta v4
PlexBMC Helper 3.4.7
Kodi 14.2 Helix

I have My own library and 2 shared with me.
On all clients I have my server current master server set to my system.

When I go to play video to a remote PlexBMC device (running PlexBMC Helper), on the device I get a script failed error.

I've trimmed out some portions of the log to save space, I can re-add (such as the full xml of the play list, or my full URL with tokens etc)

Here is another log dump I just ran, PlexBMC set to info, and debug in helper enabled.

Can anyone assist? at one point I had this working some time ago, but I can't determine when it failed and what caused it.
I have several client devices (between Android, FireStick and Windows 8.1) they all inhibit the same Script Failed error with PlexBMC Helper when trying to cast to them.
Some other side notes, in PlexBMC Helpers Config, I do have a different name then the Device name set.

Any assistance would be greatly appreciated.

Thank you.
