Hmmm... it could be that for some reason one of your security programs (anti-virus? firewall?) is blocking port 995.
Other than that, I don't have a clue, sorry.
What you could do is testing the POP3 access via Outlook, in case you have Outlook of course. See the next URL for instructions:

(ps: you don't need to install Outlook Connector as suggested though)
Or, if you have Outlook Express:

If those fail too, then all you're left with is making a post on the official Windows Live Solution Center > Hotmail:

And aks why you can't access your Hotmail account via POP3.
