Tom's currently very busy, so you've got me instead :)
As you can probably see, there's not very much to see in that logfile. There are two possible reasons. Either the download became corrupt somewhere on route (I've just tested it, and the file's fine, but sometimes stuff just gets corrupt during transit), or there's a problem with the tool. I would like to first check the "lost in transit" possibility.
Can you please delete all of the SFCFix related files, script logfiles, etc. from your Desktop/downloads folder, then follow Tom's instructions exactly as before. We'll see if that fixes it, if not, we'll work something out :)
