After my brother got the XP computer up and running, i decided to update lots of stuff that hasn't been upgraded in so long, i upgraded Windows Live Messenger, and i kept getting this error message and i kept getting signed out afterward, why does this happen and is there any way you guys might know how to fix this?

Also, at the bottom left, you can see someone talking to me, apparently, i can talk to people while i still have the error up, but i get signed out after hitting the Close button on the error window
