My Black Maxx tuner will not download to my truck.

I have a 2013 6.7 powerstroke. I am trying to install a black maxx tuner however, it only gives an option for 11-12 6.7. I have purchased the update software but it doesn't seem to have the right files. The tuner says unrecognized part number and gives a code number DC20HSP.BM. Anyone have this problem or know how to fix it?
