From everything I read, it seemed like whatever problems people had were minor. I'm disappointed to not even see my issue anywhere here or elsewhere on the internet. I create the disc and restart. I've tried holding C and holding Alt at bootup, with no difference in result. My early 2009 Macbook boots up from the CD. I see the progress bar fill up. The screen flashes a couple of times. Then the CampTune logo appears again and then it disappears, leaving only the blue background. It seems like the program should just start up at that point, but it's not. I've waited as long as 15 minutes. The CD spindles down, I hear no activity from within my laptop. I have to force it to shut down and unplug the battery to get it back to being able to boot up in OSX or Windows 7.
