Somehow, when importing Navigraph into the correct X-Plane folder, it manage to get associated with Adobe Acrobat reader and now all .DAT files are being linked Adobe!
I'm using WIN 10 Pro and despite several attempt to get MS to give me a useable fix, I've still got this 'association' to the .DAT files and can't remove it.
Is there any other App or default Windows program (Notepad perhaps?) that I can use and set, so that X-Plane can read the data and I can get back to flying again?
Regards.
