I deleted my X-plane 11 folder. Had a Vulkan error message that would not go away. My folder contained many payware planes and was also at 120 gig. I reinstalled X-plane 11. I downloaded and added AVI-TAB. When I went to see my location at the airport I was at all the folders were empty. After installation I never received the link to my account at Navigraph. Please help.
You might try re-establishing Navigraph Account. In X-Plane Plugins menu, Toggle Avitab on, select Providers, re Link Navigraph Account. Open Browser, enter your Navigraph details.
