I've never had this problem happen before and I don't see it described over on the 'Comments' page (where I'm only seeing 6 comments ending at 8:19am, btw):
The program installed fine and I unticked the box to prevent it starting, but when I finished and then attempted to Activate it, it went through the screens indicating it had activated successfully, but then I got a box stating my 14 day free trial had ended and it wanted a Registration Code or money to purchase it. The program didn't even start behind this box - just those two choices or "Quit".
I tried uninstalling and re-installing, but the same thing happened! Anybody else having this problem or got a solution?
