booooooooooo... dude i hate pinnacle... i used it for like 6 years. then i went to install it on my laptop and had the same problem as you, but didnt care enough to get it fixed. then 2 weeks later i got final cut, and my life is so much better now.
also vista is the biggest joke ever. if only pepakura would run on my mac, i could just throw my laptop away...
