Workaround for the MSDN subscription login problem
if you're behind a firewall and you're trying to access the MSDN subscription site, you might get a "The page cannot be displayed" error when trying to login, the page it redirects you to login is something like
https://profile.microsoft.com/RegSysProfileCenter/wizard.aspx?wizId=b28a479f-4189-428a-8f89-4ace6507a68c&lcid=1033&fu=https%253a%252f%252fmsdn.microsoft.com%252fsubscriptions%252faccount%252fManageSubscription.aspx

to work around that, and be able to login, first navigate to this site:
https://login.passport.net/ppsecure/uisecure.srf?lc=1033&id=42814

and login there using your passport information, then on the address bar paste this address:
http://msdn.microsoft.com/subscriptions/?lc=1033

you are now logged in to your beloved MSDN subscriptions =o) (notice the sign out button), to get to the main page you would normally get if you logged in normally, just click on the left on the "Manage Subscription" link
