This is a clip from the solution provided by, TACK and is indeed the simple software solution to the Controller Warning Message:
"... you have nothing connected to 4 and 5 then you just need to click the little green circle it will turn red ..."
That's it! No restart, no customer support -- thank goodness Tack put a little more attention to the software.
If you have more than one controller, and they are not daisy chained (####, even if they are . . .), use the same method for all.
