I get to open it two more times then it's back to where I started.
I think this will fix it:
When presented only with "register later" and "register now" click "register later" then go up to the menu screen at the top of whatever application you're in. Let's say it's Photoshop - that's where I performed this action, anyway. You'll see the "help" tab next to "window" up there...click on "help" then click on "registration." There it will give you the three options again "Never Register" "Register Later" and "Register Now." Make sure to click "Never Register" here and you'll never be prompted again.
