Hello again !

I need to change some parts of my words to a specific font but I can't change de font. I already installed in my PC but isn't work.

My code to this fonts is:

p.tres{
  font-size: 80px;
  line-height: 0.9;
  font-weight: bold;
  font-family: din-2014;

}

The name of the Font is "DIN" but I didn't find a way to make it work. Sounds to me like that font that I need to use is a little more flatten.

I attach one picture to show how it's show in my website and how should it be. 

Hi. Where is this text? I don't see on homepage
