Well, it's not entirely an error message but a blank pop-up which has the Flash logo on the upper left side of the screen with the words: "Adobe Flash Player 32" on it, and below it were, 'File, View, Control, and Help'. I guess it's probably because I haven't installed a projector for it, so I suppose that's why it didn't work, though I'm honestly not completely sure.
Oh, and by the way I've downloaded the Flashpoint, and the game totally works works now! I can finally play the game again. Thank you so much for the link! :)
