There are a few ways that has caused this
problems and the basic solution is only time will fix it.
If you get a message saying that there is
already a session logged in, Close all browser windows
and wait 15 minutes.
If you get a message saying you have locked
your self out because you've logged in wrong more than three
consecutive times. Review your setup letter, keeping in mind
that usernames and passwords are case sensitive. Again wait 15
minutes and try again.
Unfortunately we can not reset or restart your
specific control panel under these circumstances.
