Cannot login to my site

I forget which version I have but here is what I think happened.

When I try to login to my site solecollector.com/shoes/wp-login.php I sometimes get to the login page although it doesn’t look like the normal one. Then when I try to login it brings me to the following page solecollector.com/live/archive/wp-login.php and comes up as “sorry this page doesn’t exist.”

So somehow I think our original URL of solecollector.com/shoes/ was replaced by solecollector.com/live/archive/ and therefore I cannot login. Is there anyway to re-set it back to the original URL and get back in?

Thanks in advance.
