I did have both of the keys written down at one point. But recently I was the victim of a house fire, and a lot of important documents (including those keys) were destroyed.
Performing those steps did not give me a resolution. Just to be safe, I purchased a new hard drive, and reinstalled W7 on it. Nothing was wrong. I reinstalled MSE, and only then did I get the error again. I have since uninstalled it, and the machine has not become unresponsive since then. This indicates to me that it's likely an error with MSE and the current configuration of my machine that is causing the issue.
