Why can't I get into My MSN?

Question

For at least 2 weeks, I haven't been able to get into My MSN. I keep getting this:
Your request could not be processed at this time, please refresh this page or try again later.
Also, the page looks strange, the Bing Search engine appears, but it only shows the tops of the words in it.

Nothing happens when I refresh the page, and it won't even let me login; if I do manage to get to a login page, nothing happens after I sign in.  I use Windows Live Email which seems to come onto my computer ok, but I can't get onto the My MSN page at all to do anything. I have Windows XP, use Mozilla Firefox 3.5.4

Can somebody help me??
