I just got Cooking Academy as a gift, and have been playing through it, and every time I get to the 5th step of Blueberry muffins, the application unexpectedly quits. I've tried playing it off the CD, and off a copy on my desktop, and it does the same thing every time. Any suggestions? I've installed all updates, and I'm playing it on a MacBook running OSX 10.5.8.
