Naw, I just looked, the manual patching is probably too much for you... Editing and replacing explorer.exe in situ is tricky, and he gives no instructions on how to do that, he just tells you the three bytes that need to change.

First, make sure you're going to his Automatic page by using Internet Explorer and not any other browser. Second, makes sure that you've got the security settings configured to have it prompt you for activeX controls (as opposed to blocking them outright). That should do it for you.
