just got back on a computer after a few months of it being sold, and since that time windows live messenger had updated and i had to go through the standard rigmarole of updating before i could use it. i updated, no problem, program worked fine. about a week later (now) i try and log in and it comes up with error 80004005, that is that i dont have a valid IP. just wondering how i would go about fixing this...any help would be great
