This is the right way to play it. I got it out of a guitar world magazine, so I know its right.

Intro and so on...
LowE---7-7-10-7-5-3-2---7-7-10-7-5-3-2-
Palm mute this. Play this a couple of times. 

This is the Chorus
Only strum from the D string down.
HighE-7-7-10-7-5-3-2---7-7-10-7-5-3-5-3-2-
    B-7-7-10-7-5-3-2---7-7-10-7-5-3-5-3-2-
    G-7-7-10-7-5-3-2---7-7-10-7-5-3-5-3-2-
    D-7-7-10-7-5-3-2---7-7-10-7-5-3-5-3-2-
Play this twice. Thats the chorus.
