Need an instrument fixed - Help!!

Hi again! "Bad Weather" Heather here.As mentioned in a previous post, I spend a great deal of time flying the DC Airways, N1776, DC-3.I am utilizing the aircraft that members of their virtual airline download for the checkflights but I have switched panels back to the old R4D dual panel.Now, when i go to change VOR/ILS frequencies on the overhead panel, I get the audible click but no change in the numbers. i have to go into FSNavigator to make these changes.By moving various files around, I have obviously created a SNAFU for it worked before.Where would I go and/or what configuration files would I look into and what would I change to correct this?Any help would be greatly appreciated.Sincerely,Heather
