My tumblr will not work at all

My Tumblr will not work. Everything is boxy and I can't click anything. I can't login or even send a letter to the creators. Everything is different, stuff is not in the right place and I can't do anything about it. The only thing I did before this happened, was change my URL. PLEASE HELP.
