I have the same problem as maestro72x. I have followed all your steps to the word but it doesn't load anything. :(
EDIT: I got this working but only by deleting out the "default.lua" file already in the folder and then renaming the "Logitech Extreme 3D Pro USB.lua" to "default.lua" if the game is open already then close and reopen- not the nicest of fixes but a temporary workaround for anyone wanting to use this.
