PVR keeps disabling

Hi All,

I get an intermittent message that “The add on could not be loaded”. At this time the PVR clients disable themselves. Any ideas? I have only had the box a few weeks, and all was well initially, but it now seems to disable the PVR at odd times.

Any thoughts?

P.S. If this is a totally obvious answer, apologies – I am no software expert.

Many thanks!
