Hi Guys ive been playing PMDG and FS2Crew for ages and today when i load a flight and do flight planning when i click on a checlist and hit my main button nothing happens, my assignment is set up for both i dont understand whats wrong, i installed Ultimate Terrain USA today and UK2000 Heathrow Pro but these are scenery addons and everything else works, i hear all the sounds from FS2Crew, just this problem, i even tried using a keyboard assignment and that didnt work, any ideas??

Hello Aaron,So it just happened out of the blue?I suggest re-installing the PMDG 747 and FS2Crew. It sounds like something, somewhere, became corrupt.All the best,Bryan
