So far, the overlay app runs. TheWay.lua and Export.lua are in "Saved Games\DCS.openbeta\Scripts", with the specified line added to the latter. I've run the mod in both multiplayer with Player Exports enabled, and in single player.
I'm using the F-16C. The app recognizes it.
I set a blank steerpoint 50, then use the overlay to save a few new coordinates on the F10 map. After disengaging the cursor, I hit "Transfer to DCS." The app accesses the STPT screen on the DED, skips over latitude, flashes a few times on longitude with a string of numbers that are close to correct (it never lasts long enough to confirm), and then stops. None of the new waypoints are entered for steerpoint 50 through whatever—they're all still zeroes. It doesn't work if I leave the DED set to steerpoint 1, either.
Love the concept, and the interface is great. When it works, I expect it will be a must-have. Any ideas?
