Thinking about it now, ChessV only determines the capabilities of an engine when it first sees it. If ChessV had already discovered Fariy-Max and then you add support for Frog Chess, it won't know.
Click the Engines button on the main screen. Select Fairy-Max and click Remove. This does not delete any files. If you have MaxQi and ShaMax in the list, you will need to select and remove those as well (because they are in the same folder.)
Then close ChessV and run it again. It will re-discover the engines in that folder. It should then show up. You can click Engines, select Fairy-Max, and click Properties. In the bottom-right you will see a list of the variants that it supports. Make sure the name in that screen exactly matches what you put in the XBoardEngine variable.
