Hey guys this just started happening yesterday and it is happening with both Live and 7.5. Whenever I try to login I get one of two error messages saying something like "the service may be temporarily unavailable" OR "you may not be connected to the internet".
     HOWEVER...I checked the sevice status page and it says everything is up and running, and I am able to get onto the internet and log onto my email...just not MSN. All my friends are saying their MSN is working fine so its not the service...ALSO my brother is able to sign onto his MSN from MY computer but for some reason i am not...so it cant be internet connection. What the hell is wrong? Any Ideas? And yes my password is correct. Thank you.
