Hi, I've recently installed FS2Crew NGX Reboot for use with Prepar3d v3.1. I'm getting the SDK error when opening the Main panel. I have followed the advise in the Ops Manual regarding this error in FSX ie. Uninstall 737NGX, delete files in simobjects folder, reinstall 737 NGX but the error is still occurring. I have searched this forum but can not find any solution. I would be grateful if someone could help me out.
