I've been trying to read about this issue, I've watched youtube videos on installation and setup - but for some reason whenever I double click the application, it doesn't give me an option to enter my key, it just auto opens the authentication failed message and closes the program when I ex out of the message. I have yet to find anywhere to enter my key into the program. I have already purchased the key, just need help getting the program to work or load properly. Any help? Thanks!
