I'm guessing you're using a cracked version, because otherwise, as zenox said, it would make no sense not to update. (if you do have a license just ignore this post)
I'm not against using a cracked version at all, as it allows you to get a good look at the program before making the dedication of a purchase. Did it myself aswell (sorry Scirra
That being said, if you're familiar with the software and you're gonna truly use it (if you're building adds into your game you've definitely past this point) you should buy a license and support the people who worked hard to build this beautiful engine since you're going to make money of it.
