Alright. I've tried every single thing that I have read in the tech help forums. Nothing has helped me. So, here is my beef.

Download, fine. Installation, fine. Update, fine. But then, when I try to run the updater it says an error has occurred. I get this little popup thing saying that DEP has blocked a program. I attempt to edit my DEP settings to make it compatible with the setup. But it tells me that that program HAS to be ran with DEP on. So I decide to try running the game without the setup, just to see what will happen. But, of course, an error code pops up and it asks me to save a diagnostic file. But here's where it gets tricky. Every single time I open it, it's something new. It's never the same code twice. As I said before I've tried everything I could find. There are no other bug reports like this that I have found. I have all the proper system requirements, I run on Vista.

EDIT: Nevermind. Solved it myself. Found out how to uninstall it and rebooted. Now it works perfectly.
