Msn messenger keeps signing me out?

I've searched and no one seems to have the problem that i am having not only does it sign me out constantly it can get to the point where every time i send a message i get signed out or when my friend tries to share a photo it signs me out immediately before view and if i try to share one it goes gray and doesn't load. sometime after installing it and messenger plus it works for a while (tosses messenger plus and not going to use it again) it starts to work again but only till i sign out and go back in then i cant share photos and log out every few seconds or minutes i tried adding ports, changing my pass, running avg, removes Messenger plus, reinstalling and none of them worked please help (by the way i have the latest version)
