I've downloaded the game and it runs fine, but just after the scene right at the beginning where you parachute down with your umbrella collecting pies, the game locks up on the card for the next level where it talks about him climbing back up the building... Anyone else get this problem?

I've not had this problem myself but I have seen other people report the PC version of the game is technically a bit of a mess. I can't vouch for how true that is. If you want people to help you out with your issue you might want to put down your PC specs here.
