I was trying to reply to an existing thread and included the TeX script for the square root of 2 between dollar signs. The software included that but then got hung up. There was a message about Mathematica being stuck on a script. So I disabled the script but then I could no longer enter anything. So I copied out everything I had typed, closed the window, and deleted my browsing history (Internet Explorer). But, even with that, I can no longer load that particular posted question. It just waits. I can load other questions, it is just that particular page.

What can I do to recover it?
