I keep getting the same error everytime I try to start World of Goo, it freezes while the white text is scrolling up the black screen at the beginning. I downloaded and installed the game through the game for windows live client, it ran fine 2 or 3 first times I started it but ever since then I have been unable to play. This is the error message:

I am running Windows Vista fully updated. I have tried running the game as an administrator and with several different compatability modes but nothing has worked.
