Error 404 on Login

Recently I started having problem with my login. Whenever I try to login to my blog, it returns a Error 404. Since the last week I’ve searched through all the ways on WordPress, and other blogs on the internet to deal with it but nothing worked. I thought that my blog could have been hacked, so deleted my waremania.tk.

I thought to start up it again, but with a new domain windowshub.tk, but after Installation, I couldn’t go further after “Success! WordPress has been installed” Page. When I clicked the ‘Log In’ Button, it returned the same Error 404. Please Help.
