I have brand new Saitek Radio panels - two of them - running on an XForce PC (also new) and when Xplane is initializing, the Radios and Multipanel light up, but when Xplane is loaded, they go dark. The test app demonstrates they work, but I cannot get them to work in Xplane. I have 6 FIPs and they work great. Also Yoke, throttle quadrant and pedals work great. I followed the PlugIn directions but must be missing something. Thanks in advance for any help.
