I have found out how to download it. This is the only method, and it will require some sacrafices. However, it's nothing major. All it will do is clear your game updates, not anything downloaded. You can just get the updates again, for free. In order to download it, you must clear the system's cache. In order to do this, go to the 360 dashboard, then go to the system blade, then to memory. Next, when you see the option to view your hard drive, don't. Instead, just highlight the HDD (hard drive) icon; then press Y, X, X, LB, RB, X, X. This will allow you to download the Beta! Enjoy!
