Bishop lvl 120 Mount

So, after not playing my bishop in over 6 months, I logged in to it today and my mount is gone. I still have the things equipped, but for some reason, I can't actually use the mount. Obviously, I'm doing something wrong. Any ideas, suggestions, thoughts?

Open your skill window and click Mount (or Riding)~

Your mounts are now in the mount skill section.
That can be accessed through your skill inventory (bottom center button) or through clicking on your character and viewing "mounts" (bottom center-right).
You can drag those onto your keyboard.
