What is the chord progression and strumming pattern to The Mortician's Daughter by Black Veil Brides?

The first set of chords use is C Am F G. When you reach the chorus, you change to C G Em F and then do it one more time and start with C Am F G again.
Strumming pattern is DOWN DOWN UP UP DOWN... Same pattern through the whole song. << Wrong. I think you'll find it sounds right using Em C#m A9 then Bm on the verses, then for the chorus Em B G#7 A9. Enjoy. It's right this time :)
