Need to upgrade DJay?

I purchased Version 4.2 and had no problems, until recently when I went to launch it. It said I need to purchase it again. I have a License Key Code but wouldn’t accept it. Was wondering if anyone had a similar issue? Does the old version not work anymore even though I have a License Key?
