Hello!   I recently downloaded the A318-A319 Aerosoft X Professional Aircraft Pack, and since I downloaded the program, I have had problems with my Right MCDU. The right MCDU is not stuck, but I can't find how to go onto the actual MCDU2 Menu where you can open doors and load fuel etc..

Attached is an image of my problem. It just shows this message everytime I load it up.   I'm using P3D v4.3 by the way. Thanks!
