i cant log onto msn it says the service is termporarly (spelled wrong) unavaliable and it gives me an error code 81000314
Reinstall MSN? Hm..reconnect to internet. I have also sometimes MSN errors without any reason xD Good luck.
Not sure what you can do, other than that, make a new email, and just email all your friends/family/etc your new one. Sorry i couldn't help futher.
If it says temporary unable to blabla... Try doing this: ctrl+alt+del and remove msnmsgr.exe and msmsgs.exe out of your process thingie. Restart msn.
