It's something with IE. I had this problem when I updated a while back. Service pack I didn't do anything 'weird' for me, but there was a hot-fix a while back. What I had to do is go back and clean out all my temp files, delete the cookie for Renderosity (and a few other sites), and then flush the Cache directories. After a reboot, or three or four, things started working again. What's really strang, is that even after this, it just "started" working again a couple days later. No real clue as to exactly which step cured it... but something in all of that kicked it into gear.

The doctor says I have way too much blood in my caffeine system.
