Can’t login after MT import

I installed WordPress on my server and then imported all of my MT entries. I specified the user that I wanted, in this case: BlueBeetle. I then tried to login with bluebeetle and the ‘changeme’ password but it doesn’t work. It just goes back to the login page… and of course I don’t remember what the random admin password was. Is there anyway to get in or do I need to reinstall WP?
