Help! calendar stuck in "2005 mode"

Maybe someone can help me here.

I am not sure what the problem is, but my Hotmail/Outlook calendar seems to keep loading the old-school version. Everything else I do on looks great - email, skydrive, etc., but my calendar keeps loading in "2005 mode."

I want to switch back to using my Hotmail calendar since Google Calendar support is going away in Windows 8, but I keep getting this ancient calendar interface. It barely shows any events, it is painfully slow, and it takes way too many clicks to get anything done.

Has anyone else experienced this? Why does my calendar keep loading in "2005 mode"?!
