Hi guys, after having to follow these instructions (Cam's post 79) again, after installing the patch, it all initially worked. My suspicision that I'd already done it and during the day, after a reboot, I had to repeat it, were right. Today, when turning on my PC and loading the CRJ, the same thing has happened - Plane flies fine, but none of the MFDs/screens work. I will go through the install again, removing the C++ package, reboot, reinstall and let it go through the motions so, eventually I can fly again. But it's gettin boring, doing this every day. Possibly the package is being modified on reboot, changing something crucial that means the plane won't work? Details, along with attached log.txt. Windows 7 I'm on Xplane 9.69 You'll see plenty of plugins installed, but the x737 is not in my aircraft directory, backed up. Once I get the clean C++ installed, everything works fine.
