I followed the instructions from this link (http://superuser.com/questions/125931/how-do-i-install-myst-4-revelation-on-os-x-10-6) to the T on this website.... after I installed the game and tried to play it i got this message.....(Myst4 Revelation quit unexpectedly) it gave me the chance to reopen it but every time i tried it did not work. Can any one help me with this problem thanks.
