Thank you all for responding. So far, no luck. When I plug the firewire cable a dialog comes up that states, 'Attach Camera - The camera could not be attached'.
I am using a 6' cable.
Going to the Preferences Tab > Camera (Icon), I see the following:
Phase One and Leaf Credo Configuration: Extension - IIQ
Leaf Aptus and Aptus II Configuration: Camera - Contax (Obviously I do not have this back, but no other selection other than Contax exists here).
Live Preview: Pause After - 30 seconds
Providers: Phase One / Leaf Credo, Leaf Aptus / AFi and Nikon are selected
I will have to make a case at PhaseOne support as David recommends. I will order another cable in the meantime just to double check that it is not the cable, but not being able to tether to the computer is going to be a big deal for me as I want to use the P40+ back on both my 645 DF+ and my RZ67 Pro II D tethered while in the studio.
Might it be that I am running a 30-day Trial version of the software? Is the P40+ back not supported anymore?
Off to bed now, and will come back when I get some results and/or when I hear back from PhaseOne.
Thank you again!
Chris
