Yes, sir.  I did by mistake during my first learning session.  I was trying to add a new login field of "zip code" and I think the mistake is when I set the field to be an integer, then had the default text in the box set to "enter zipcode here," but what do I know.

All I know is that now, after I go to login as admin, it pulls up an "Please update your profile before continuing" screen with the zipcode entry there and -1 entered in the box.  No matter what I put in there, it returns the aforementioned error (and now can't get in as admin whatsoever). 

I am in the playing around stage now trying to learn some ins and outs, so no big deal, as I'm going to start again after I blow out my new laptop and get ready to build a couple portals.  However, is there an easy fix?  I would assume I can go into one of the files with the security settings and pull it out, but I can't seem to locate it (not really sure what I am looking for, either).  :)
