Press the Start orb on your computer, in the box type %appdata% click the "roaming" folder, Go over to .minecraft, open the .bin, then open minecraft.jar, then close everything but minecraft.jar, Next, Open up the mod file, Highlight everything the file except the folder named ".." Drag the mod files into minecraft.jar. Boom! :D Delete a folder named 'META-INF' If you have not already. Hope this helps! :)
