Are you still having the issue with no formatting? It's just a glitch that occurs occasionally with a variety of websites, but usually seems to go away pretty quickly on it's own (from a user perspective).
If it's sticking around, try clearing out you IE history and cookies and then restart IE.
Please let us know if the issue continues. Thank you!
