Go to AppData/roaming/virtuali/airplanes - In this folder find the CaptainSim folder with 767 GE engines and open the gsx.cfg file with notepad. Under [aircraft] see if you have the line nosegear = 20.88. If you don't or if the value is something different, make sure it's 20.88 and you should be good. Also, make sure the line bypasspinpos = 0.00 0.00 0.00 is there.
