Gerrit account broken?

Hi guys-
   I just noticed that I couldn't make a push to Gerrit from a different machine than the one I'd been using.  So I went in to my account on it and noticed that it appears my username isn't set any longer.  I had done this before, but now I tried to set it back to what it was and it throws an error "Username must contain only letters, numbers, _, - or ."  The username I was using contained only lower-case letters, and was 9 characters in length.  I double checked for any leading/trailing spaces, etc...

   Anyone know how to resolve this?

Thank you!
