Who Can Help Me?

I am so frustrated with this blog thing. I just tried to change my background because the one I was using is no longer available. I found the perfect new background and changed it successfully. I then tried to find the place to change my font colors and now my entire blog is lime green....NOT the new background that I picked. The layout is totally different and my list of friends and MG's ticker are gone. I am so FRUSTRATED! Please some one help me!
