I copy and pasted the license from the download section that I was given when prompted it. The error message I receive is "Received an invalid confirmation code from the Esenthel Authentication Server. Please make sure that your computer has a correct date,hour and time zone set.".
I am also unable to log into the store page of the editor with my login credentials.. It states "Invalid Password. Please make sure that your computer has a correct date,hour and time zone set."
Obviously I've made sure that the license code I entered was correct, my password is correct, and my time settings are accurate. Unless I have missed something, It would appear that either your license server is down, or I am simply having trouble connecting to it.
