I went to the store today and bought one. I didn't want to wait until Monday for the mail to come. I am currently tripple charged until the returns all hit, but I didn't want to blow the weekend when I could be using this down time to be setting this thing up so I am ready to go...
Guess what, the back popped off the first time - easy as pie.
It works when it's not busted.
Thanks again for all the tips and video - as I said, I'm sure it will help others who search the forum if this happens to them. But if it is too hard - it's busted - return it and get another one.
