<Alter Login sa - SQL 2005 - Login Failed>

Hi all, i issued the alter login sa name = [xxxsa] on SQL Server 2005. After
doing this, i cannot login using the sa or xxxsa user id. It keeps telling me
that login failed.
How i can i login back?
Thanks
I figured out the problem. When i changed the login to xxxsa, SQL Server
changed the login to 'xxxsa' (with the quotes). When i used the login with
the quotes, it worked.
