Are you getting the error when downloading from here, or the megaupload site? Because the file on this site is just a text file telling you to download from the megaupload site.
edit: After watching that youtube vid, tomorrow's races should prove to be very interesting. I don't have time to try the track tonight, but will tomorrow and hope the grip on the pavement matches what I just saw. Need to practice not flipping around those hairpin turns hahaha.
