Airbus 380

Hello All, I have downloaded the Airbus 380 by Robert Versluy it comes with the default engine sounds and the default 747 panel and everything works fine, I have installed a Airbus 340 panel and again the panel works ok but when loading the aircraft though the stages it takes a long time to load , at first i thought the sim had frozen but waiting a minute or so at each stage it finally gets there, Obviously its to do with the 340 panel i would think as installing the default 747 panel it goes back to loading normal, difficult i know to say whats causing it but any thoughts would most wecome, Thanks, Dodger.
