Brian, Your suggestion to uninstall and start again seems to have done the trick. Both tuners set up OK and two concurrent test recordings were successful.
Many thanks
Alan
BTW, for reference (if you don't know this already) - when you setup the Nova-T, it should be another Device #1 (not #3) as it is the first instance of its kind.
Thanks Brian, thought as much but nice to have it confirmed. Probably set the Nova-T up this weekend now the Pinnacle is working properly.
Regards, Alan
