(This is on a mac). I had done this previously but cannot seem to get it to work any more. I can download a map or scenario and when I choose it it opens in the editor, which seems fair enough. What I can't seem to do is save it as (open it as) a playable game.  What have I forgotten?

I have previously observed that the choose dialogs are confusing in that I have to triple click the download folder in order to see downloaded files.

In the game setup, in the dialog where you choose the map maker, you can also load a scenario or load a map.

I'M RUNNING SONOMA ON M1.  FROM PLAY SCN, CHOOSE MAKE A DIFF CHOICE, CHOOSE MAP OR SCENARIO, IN MAPS CHOOSE DOWNLOADS (A LITTLE TRICKY) OR MAPS LISTED, MAKE CHOICE, MAKE PLAY ADJUSTS, AND PLAY!  I'VE NEVER HAD AN ISSUE.  HNY!  GOOD LUCK!
