F3 PVR Problem

[rjm41]

Hi all
My f3 was working fine a couple of days ago.the pvr functions were working fine.
This morning I plugged in the USB stick
And tried to pause the footy, the f3 did not detect the stick.
On removing the USB stick, it tells me the device has been removed.
Tried another USB stick which
Innow worked a few days ago, but the same thing is happening.
Any ideas??
Thanks

Have you checked that timeshift is still enabled, it might have some how become disabled.
