Hi! I must say I really love this product, and thus it's a shame that I have to post this topic. I'm having really bad problems with my NGX. After loading the aircraft the panel in the VC apears and everything is fine then one of the following problems occure. 1. The aircraft loads properly but the AI-traffic disapeares and you only see the shaddoes of the other aircraft2. I can't see the ATC window3. The NGX disapears in the same manner as the AI-aircraft (but the AI aircraft are uneffected)4. the NGX partly disapears. Parts of the engine and gears disapear.5. everything is working fine but all of a sudden the whole screen goes black and you can't see anything, just hear the engine noise.6. every now and then everything runs perfect and the next day it doesn't. Can anyone tell me what I'm doing wrong and how I can fix this annoying problem. As I said I really love flying this aircraft and it's so sad that this problem spoils the experiance. I've tried reinstalling it and tried running it as admin and also chosen not to use it as a default aircraft but the problems remain.I'm running:vista64 SP2Intel®core2Duo CPU E8500 @ 3.16 GHZ 2,83Ghz4gb ramGraphic card:NVIDIA GeForce9800 Thanks for any help!Dhammika
