Your site loads for me now, so it seems your account is somewhat active again and should be fully active after the full 2 hours. After that time, if you still get the 'unable to login with that username and password' error, you can use this page to start the password reset process: https://heliohost.org/reset/
The password reset email may not arrive immediately, so be aware of this before trying a 2nd time. A 2nd password reset attempt will cancel out the 1st one, so it's good to wait a little bit to give the email time to be delivered.
