Panel problem with DHC-2

Hi,
Does anyone have Fred Banting' s DHC-2 Turbo Beaver? Have you experienced any problem with the comm and nav frequencies? IN fact they don't seem to change even the knobs (+/-) are located and pressed accordgingly, the display does not change. The other parts of the radio stack (ADF, Transpoder) work fine. I have installed the "on wheels" version but I think it is the same for the rest (same gauge, same panel.cfg).
Thanks in advance for any help.
