Base.css is f***ing my links up!

Hello everybody. I have a problem that is driving me totally insane!
Link to my site

I have some links on my webpage, which all gets their style from base.css. No matter what I try, I CAN NOT make any style or css, that overwrites this stupid line:

a:link,a:visited,a:active {
color:#2a282e;
text-decoration:none;
outline:0;
}

If you look at my site, it’s the bar underneeth my slider, where it says “Download”, I want to change that color to white. Buuuut, if I change the color to #fff in base.css, it changes the “headline-links” I get when I search on my page!

Please, tell me there is a way to change this!
