How come my yahoo messenger won't sign me in?

How come yahoo messenger doesn't let me sign on?

• I have my sn and password saved on the computer, and i sign on to yahoo messenger after i sign in online everyday. Today, however i couldn't sign on, regardless of what i did. I even uninstalled yahoo and then reinstalling everything. I even changed the password to make sure it isn't b/c of wrong password. It says yahoo was unable to connect, exactly what does that mean? I tried changing the proxies setting, that was of no help...someone help...i have run out of options...help please!
