Windows Live Messenger ~ Wont Connect

Well I recently hit a snag when trying to use a script in the newest windows live messenger, which for some reason deleted the .dll file so i thought that if i removed windows live from my computer then i could re-install it. However, everytime i tried to re-install it a message said i already have messenger etc. so i deleted windows live from my program files and tried it again, still nothing.

So now i copied my friends windows live folder and e-mailed it to myself and pasted it in the program files. I clicked on messenger and it came up. I tried signing in but it just said "signing in" for around 30 seconds, which is weird because it usually signs in after about 5 seconds, and now after those 30 seconds a message pops up saying "we can't sign you in to windows live messenger" and "there might be a problem with your internet connection. Make sure your computer is connected to the internet."

And i know it is connected because i can easily sign in to ebuddy without any problems whatsoever. More information says i have
