This is from my X-plane 11.11 Log. All other plugins work fine such as WT3 and Ground Handling, etc. I have tried to reload version 1.50, 1.51 and 1.52 of the Ground Traffic plugin without success. It was working fine until today. Not sure what changed but I did update X-plane 11 to the latest beta version but then re-updated without the beta but still no Ground Traffic. I am running Windows 7 64 bit.
LOG:
GroundTraffic: This plugin should be installed in a scenery package folder!
Failed: F:\X-Plane 11/Resources/plugins/GroundTraffic/64/win.xpl. (The plugin refused to start by returning 0 from XPluginStart.)
