Airline Pilot 1 - German Adventures - Problem

Hello,

I have a problem when flying the Adventure LH1418 from Hamburg to
Dusseldorf. During radar vectoring approaching Dusseldorf I'm told to
contact the Dusseldorf Director. Unfortunately I'm not able to
establisch radio contact with the Director, and so I just have to land
on my own without any ATC-guidance.

Maybe there is a bug in the adventure giving me the wrong frequency
for the Dusseldorf Director. I'm hoping for help, because the german
Airline Pilot 1 adventures really are very nice and realistic!

Regards
Isak
