I am trying to install Creator 2010 Plus on W7 64 bit. I have installed this software before on a different computer, but I've long since UNinstalled it on that PC. I bought this software. I have the product key from the inside of the box. It keeps saying that the key I'm typing in is invalid. I've tried and tried. I've got it right, but it won't accept it. It's a 17 digit key. All letters are caps. Again, I'm typing it in correctly. I would appreciate any help.
