I've updated the mod files to incorporate the tweaks I mentioned in the dev log before, so try downloading it again. If you don't mind losing your progress in the game, unzip a new copy of the original game somewhere. Move the mod's zip to the www folder. In your zip program (I use WinRAR) click "Extract To" then enter just "." (without the quotes) in the "Destination path" area - or whatever works in what you use. Allow all 58 or so replacements. If that didn't happen, it was done incorrectly. That's about all I can do from here to get you through installing a mod.
