Help with loading a game.

[Xelief]

I've got the ISO for Final Fantasy Tactics The War Of The Lions which, at least according to this thread, is at least somewhat playable. However, once I hit "load UMD" and click on the game I want, nothing actually happens. Could it just be that the game isn't actually compatible? I notice that for the default cube demo that there's a CSO file as well as an ISO file, so will I need one for my tactics game as well? I'm using the latest build from this website and the emulator won't even open up the demo cube for me either, but the one I got from the official website will still load the demo but not the actual game. I should mention that this is my first time using the emulator and loading up a game, so I hope that this is merely an issue with the settings or something.
