My Twitter "profile" page says I don't exist! HELP!

I went to my account page and it says it does not exist, but if I log in with my email address and "tweet" it seems to work. However, my page "twitter.com/batgirlbabs" does not exist and I cannot see my @replies.

This first happened today when I attempted to change my name. However, now I cannot log on with either my old account or my changed name; only my e-mail address. People can see my "tweets" but I cannot see theirs come up on my page.

When I go to my "home" page it seems to work, but when I click over to "profile" it says my page does not exist.

When I attempt to go to my page, it is not there. : http://twitter.com/BatGirlBabs

When I log in via e-mail, I can tweet freely.

Any and all help would be appreciated! I would really like my account back for work related purposes, thank you so much!
