there is a new! i download the file but there isn't the explosion image... there's all the file that could help you to make this first program, but there is that image!!! it's better to download the explosion image from google... it isn't the right image, but there are many similar image...
i found the solution at this problem! you must open the page in another windows with a right-click on the link, then you must copy the url of the new page with Ctrl-C, after that you could download the source-file (the new page remain's open only for 1 sec. ca. so hurry up)
