Just bought the program but not sure how to activate the full version?
I think that I received the key in the email receipt sent to me by humble bundle but now I am not sure where to activate the key.

The first time you open the program, a popup should appear, in that you should be able to insert the long you received.
Can you use the program, or is everything locked?
The humble page has a link to the license page on pyxeledit.com, where you can get the activation key.
The program should ask for the key the first time you start it up.
