Okay, here's the deal. You download APE II by Sideshow Bob (which you have done). Open the zipped file and inside you will see several files. On the one marked html use OPEN, not extract, and read the guide it gives you. It will explain which other files you need to use and what to do with them. Some need extracted to your desktop. Try doing that, and it should be much more clear. Read through the guide carefully, and do exactly what it says.
You WILL have questions, so you can post them in Current Projects and we will do our best to help. :original:
