Please Help me!!

I have a problem, do not know if I can help. Over a week ago to buy a domain with hosting. Now I want to export my blog which is in the subdomain. Trying to do this in the area of the blog URL I gave my new domain and what happened was that now I can not access the wordpress platform and I get my blog in one form so ugly, the template is gone. Before that I had tested with the hosting company to see if they could redirect to my new blog address and they did but instead of being the blog to my domain did my blog on the subdomain addressdomain, so the direction that was emerging at the top of the window was the same subdomain. So my decide do it myself by changing the URL to my new address with the following results. http://tila.blogsydinero.com/ am so tired, I’ve done everything, it seems that all my work, work for many weeks it was going overboard. Nor can enter the username and password. It seems I may have to start again from scratch. 🙁
