I don't think I've received any email yet... still, you can probably fix it by editing the XML file on the line the error indicated. As I said, "Particles" is not a valid expression, so change it to something like "Particles.Count" or just an empty string like "" and the project might load. Even so you will probably want to change it afterwards because it looks like you're trying to pass that to a 'load image from URL' action.
