Same problem here. I installed fsuipc but got the same result. Maybe the problem isnt p3d yet Windows 8 or 8.1. I also got a lot of problems with the citation x in FSX. But thats no suprise, Eaglesoft writes on their page that they do not support win 8. Very sad for such a pearl as the Citation X.
Hey there I read a lot of different opinions. Some say it works, some say it won't, and never will work in p3d. I'm running Win 8.1, p3d 2.4 and installed the Citation X via EMT. Unfortunately i get a black screen after I select the aircraft. Has anybody a suggestion, or can confirm it works in 2.4? And yes, I know its not developed to work in p3d. Im not asking for support, just for clarification if it's hopeless to try or not. Best regards Yannick
