Tuner working on NPVR not picked up - log file attached

Wanted to post this in the Community Supported Tuners subsection but can’t seem to be able to post in there.

My Plex install is on a Windows Server 2012 R2 with the BDA drivers installed and I successfully have my tuner working on NextPVR and SichboPVR, and when I scan for it in Plex I can see that Plex successfully identifies it as a bda device but then seems to fail because it can’t find a file somewhere in the Plex installation directory?

I have attached the log file.

Any help greatly appreciated! Cheers.
