A person can have a blog account without a blog, since it gives them the ability to comment on other blogs even if they don't want one of their own. Blogs that have been abandoned for 2 months are usually removed.
I'll find your blog user account and delete it so you can start fresh. If you have any problems creating it or logging in after, PM me with a password you would like to use and I'll make sure it works.
Hope that helps
