I have the Couatl and GSX menu items under the "Addons" menu. But not GSX appear wen I press the CTRL+Shift+F12 hotkey
I reinstall the content , even the complete like you advise me (repair)
If you have the GSX menu, it means GSX is working properly. If you don't see the menu when pressing the hotkey, the only possible reasons for this problem are:
1) You have installed the Content. This is BY FAR the most common case, since the Client doesn't contains files to support the new P3D menu system so, it's a problem that will happen 100% of the time if you upgraded using only the Client.
OR
2) You have changed the default GSX hotkey
OR
3) Another addon is using a key in conflict with GSX
To check for points #2 and #3, try to call GSX by selecting it from the GSX menu (instead of using the Hotkey). It it works, then IT IS a key conflict or just the key that has changed.
If it doesn't, then it's problem #1
maybe Windows 10 problem ? P3D v3.3.5 professional
That's what we all use at FSDT too.
