On my 4640 display, I can't get my Raven liquid controller to work with my John Deere 1910 Air Cart. I get this "!" exclamation point by the sprayer indicating something is wrong (see picture).

Can anyone help me figure out what I'm doing wrong? I borrowed by neighbors 2630 display and it seems to work fine, just not on the 4640. The menus between the two displays are different enough that I can't figure out what I'm doing wrong. The Raven should be up to date - Software Version I just hooked the 4640 up to my wifi and did an update on that too - didn't fix the problem.

Any help would be appreciated.
