Okay, so, first things first: Download AC Web Ultimate Repack 8.0 (MAKE SURE ONLY 8.0, NOT ANYTHING BELOW) at http://megaupload.com/?d=F1DMYE8D
After you have done that, open it up. All you need to do is click install. DO NOT TOUCH ANYTHING ELSE!
After it installs, go to C:/AC Web Ultimate Repack. Go to "Tools", then "Map Extractor enUS" (if you don't live in the US, use the enGB one).
In this folder, copy the two files named "ad" and "maps".
