I have the release version 2.5.6 of DCS. I have the T-45 saved in the correct location, but when I start the game and ask of this aircraft, I get a dialog box that says the module is newer than the editor, either cancel or proceed at your own risk. When I click OK, the loading does not continue and I have to exit the game via task manager. Do I have to have a beta version of DCS to use this mod?
