I have this same problem as well. When I downloaded and unlocked the upgrade, my program showed that I had 79 templates. When I chose one to 'play' with, it told me that I couldn't because I needed to download the template pack. I did this, and then only had 49 templates.

I have gone over each step, one by one, to make sure that I didn't miss anything and there was no problem there. Why isn't the program working correctly?
