So the protector does not cover the center of the D-pad?
I did that myself with some vynil that I cut by hand, and after a little bit of use, there was some gunk from my fingers around the D-pad (where I had cut a circle out). I suspect you guys are gonna have the same problem...
I now have a piece of vynil covering the entire D-pad, including the center. I just wish I had cut it better around the edges (too lazy to do it over

)
