"It appears that the equipment is unconnected or connected incorrectly. Please check the connections."
Can't figure this one out for the life of me. Has anyone seen this error and been able to fix it? I have not altered my setup for 5+ years of using the 700r+c combo, and all of a sudden started getting this prompt about 2-3 months ago. I've unplugged, re-connected, tried every combination known to man, to no avail - help!
