Yes! I found I have version 2.23.3 with its Mission Editor, and I confirmed that that version of the editor will load and properly interpret your map. So.... if it can understand USRanger's mission, I will use it to edit in the changes (changed plane set, I'm assuming). Once the edits are done with V2.23.3, I will probably be able to use new version 2.26.3 to compile the results and you should be in business.
Don't expect much "intelligence" from the "bot" planes, though.... in my experience, these newer versions of Aces High don't allow the bot planes to fly at the designated altitudes or speeds; everything will probably be a lot lower and a lot slower than Ranger intends.
At this point, I'm just waiting for the mission source code....
