Thats probably cause nobody is emailing u J/K

Well, the same thing happened to me with my gmail account on Outlook Express. It was going well, but suddently i stopped getting mails.

Then I rechecked the settings and realized that the was a mistake, so when I corrected it it started to work, but normaly the error that happened to me is not usualy supposed to occur unless someone else screwed it up,

But meh... Its worth a try, u wont loose anything, so I say check out if everything is correct.
