pinging
www.microsoft.com returns a "request timed out" message. it doesnt mean that their website is down... it just means that they decided to setup their firewall properly to limit their exposure to hackers...
now, i am getting the same server is busy error. but when i try to use a friends account that has been playing for a few week, it works. on the same computer.
this just tells me that this "server is busy" message is the default message when encountering an error or when the server is unable to log you in in this build.
