I have installed the Mac preview. I have a new Macbook Pro, running OS X 10.8. I followed all the instructions, and install it twice. When I go to launch the program, it brings up the choice of activating by internet or using the 30 day trial. I have already purchased the 6.00 Mac thing, but haven't received the activation by email yet, so I wanted to use the trail. Every time I select it, it shuts down. Any idea what I might be doing wrong?
