installing pop cap "peggle nights"

i want to install the game on my imac, i do everything that i'm supposed to but it's not working. like a fatal error came up "out of free sound ids" and like they said, go into midi setup, and change setting to 44100.0hz, but it,s already at that setting, but unclicked the check (mute) next to audio output. and loaded the game, and it got down loaded. i played the game to make sure it was working,and it was, then closed it out. then tried to reopen and a sign came up, you cannot open "peggle nights" and i had to uninstall it. and also when i closed the game, a sign came up "peggle nights quit unexpectedly" this is a game for mac, anyone have any idea? one more thing, if i go back into audio midi setup, the mute is checked again. ??
