When I attempt to download the bike model, mediafire just says preparing download and nothing happens. What am I doing wrong?

P.S. I am a noob don't be to harsh on me.

I am new to the game and can not get the bike skins to work, am also encountering some weirdness with mediafire. I watched a tutorial from Vurbmoto and got the gear and helmets to work but after doing the same thing for bike skins It does not show up in my bike setup, I am sure I am doing something ...
