Have you installed mods before? From the mod page it seems like all you ahve to do is drag and drop it into minecraft.jar. Maybe try removing META-INF if you haven't already?
What I did is that I used McPatcher to install it. So If you can't get it to work, there's always that option. I heard that the Magic Installer is better though.

This is so damn depressing, the depositefile(namely any sites like this) keeps giving me the IP adress connection limit exhaust bullcrap and I can't download what I really freaking like. What do I do...
Give it a bit longer and post again if it keeps happening. Are you sharing your internet connection with someone else? If it continues happening, I'll upload it to a mirror site as well.
