Zgemma plexdvr crashing on setup

[demotic]

Hi guys

Hoping someone could maybe work out the problem i;m having (Hoping it's not something i've messed up)
i have a zgemmah2h (wooshbuild) the plexdvr is available in plugins and i installed it.
When i press green to *create* the box crashes. Tried rebooting the box and starting again but no joy.

I've added the crashlog file, hoping it will be of help.

Thanks for looking
