That's what I have been doing. It just says login attempt failed. I just tried with your link to make sure. Still not working.
Edit:
Could it be a password problem
One more thing I get an error message when i go to the cPanel page. I reads:
Runtime Error
line: 595
Error: 'ADBRITE.INLINE.text_nodes[...].data' is null ornot an object.
This could be the problem I guess. I've tried IE and Maxthon to open the page but still can't login.
