I purchased Fences 2.0 in April 2013. No problems until recently when it pops up that I need to enter my product key all the time. It will not take it, I contacted the company who sent me the product code, which is the same one, and it still will not accept it. I then tried to enter my email address and password and it says no such account. If this problem isn't resolved quickly, as this has now been going on for weeks, I will just have to delete Fences and call it money spent.
