Just bought Crusader HD to play on my MacOS High Sierra and when I downloaded it the first time, the mouse worked fine but I was only able to launch Extreme. I wanted the original game for the tutorial (been a while since I've played), so to get that I tried to re-install using Galaxy. Now when I launch it, my mouse doesn't appear so I have to try and click around to close the game.

Does anyone have a workaround for this? Any tips? All I want really is the original game with tutorial, then it doesn't matter which version I use, so for now I just want to be able to use the mouse! Thanks!
