Can't log into ff.net.

[yaseen101.livejournal.com]

Recently, I tried to log into my ff.net account but whenever I tried to enter my 'hotmail' e-mail address, 'invalid e-mail address' or 'please enter your e-mail address' keeps appearing. I tried substituting live and msn in place of hotmail (as per the Wiki) but that didn't work either. I'm utterly fic-blocked right now so I hope there is someone here who can help me with this.
