I have known people who had their machines screwed up by Securom, but that was about four years ago. The latest versions are nothing to sneeze at, but there is a reliable procedure for uninstalling the one that comes with Kingdoms now. A procedure that you can find with a quick search around the 'net. I personally wouldn't attempt it before I was ready to uninstall the game as well, although obviously it's been done by a part of the gaming community it would be ill advised to discuss here.
