Not got very far
It may not be the password you got wrong. Unless you changed it, the default user is 'admin'. (I often make that mistake with a new site, having forgotten to change it after creating the site)
If stuck, you can go through the lost password procedure and either get an email, or if you have no mail server connected, look at the 'Logs' table in the database to get the new password link. (But you still need to let the 10 minutes elapse).
You can also truncate (not delete) the database table 'FailedLoginAttempts' to get round the 10 minute IP ban.
