Hi Umberto & Co.,
As mentioned by many others in other threads, I too have problems after updating to the latest version of GSX and running the addon manager update. Nature of problems I have is:
1) P3D fails to launch; runs in the background until I manually kill the process
2) When I disable couatl and bglman from the xml file, P3D seems to launch OK but cannot use GSX or use FSDT airports
3) Re-installing and re-enabling GSX+addon manager enables P3D to launch OK once but fails again after shutting down and restarting.
As suggested by yourself and others, I have deleted the (empty) XPOI folder but that hasn't made a diff at all.
I understand you keep saying 'this shouldn't happen' but can you clarify how your internal tests were performed and what addons you had on your testbed?
Thanks
Sorry again, but I have very similar problem like sumits81, but I have KMEM and GSX working now, but no others. I have deleted empty XPOI folder, but it hasn't solved problem. P3D fails to launch, runs in the background if I start it from Desktop with shortcut. If I start it from P3D root folder, P3D seems to launch OK but cannot use FSDT airports , exc. KMEM and GSX. If I uninstall Addon Manager and example CYVR, and after reinstall CYVR or other older airports, I have working all others well, but no working KMEM and GSX. Who understand this?
I have deleted FSUIPC, and I have updated P3D 3.4 hotfix v3 Client only.
Sorry for my English!
