I just put Black Hawk Down on my PB. The .dmg file is on the desktop. I double clicked it, it opened up and there was a readme and a folder. Soo i dragged the folder into my apps folder for it to install. When it finished installing, i went into the apps folder and double clicked the image that runs the game. It told me to insert the cd, but i had the .dmg file mounted already. Whats going on?
