Login Trouble

Hi. I am having login trouble with my wordpress accounts on byethost.com. I can login and log out a few times within the first hour of the install, but can never login after that. The wordpress page doesn’t claim that I have the wrong password, it just reloads as if I never hit submit, but instead hit the refresh button.

I tried all of the troubleshooting options in the wordpress.org codex area and nothing worked. Should I do anything else?
