So I have reinstalled the simconnect from fsxsp2 xpack folder, Addon manager still doesnt show. The PMDG's is my problem, as they change the way of requesting weather data, now it works. So now Addon Manager is the only thing that doesnt work, thus can't use GSX, CYVR, KLAX, KCLT, KMEM, KIAH, PHNL AND KORD. Really frustrating. Do you need to look at anything to find the problem? thanks
