The issue I'm having is trying to get to the point where I can add letters for a flight plan for P3D. I know you rotate the outer knob then rotate the smaller knob to start cycling through the letters and for some reason mine just stopped working. I sit there and rotate but no letters ever come up. It has worked before then I didn't use it for a long time and now it's doing this and I was wondering if this has happened to anybody else lately? I haven't tried to reinstall just yet. 

Hi Greg,

 

I usually add the wp not with the knob but with the keyboard just below. It's simpler and faster.

 

Regards
