I can’t access my admin files, help!!

Hi all,

I’ve done something silly…The title of my blog always linked to my blog and not my website and this was something I’ve been trying to change…

I changed the URL of my blog in my options panel and now I can’t get back to it because it says the file cannot be found…How can I get back to it?

My blog is still up but it has no style sheet, help!!

Many thanks in advance!
