I can’t login and I’m administrator

I am administrator for my high school reunion forum.  I was trying to re-register with my new name, and so I deleted my old name, which was the administrator.  Now it won't let me on because it says I haven't activated myself, but I gave the forum a bad email, because it wouldn't let me register with my old email, because that would have been a duplicate email, so I didn't get the email that activates my account.  Now our forum is sitting there with no one to run it, and I can't get past the sign in.

Thanks!  I can't believe what an idiot I was to get into this situation.
