I just bought pyxel and the redeemed key doesnt work when I try to get a license.

I as well cannot seem to get Pyxel.  I got the email, but all it has is a code, and I don't know where to use it or how to get the executable.

Ah, I see what I was doing wrong, and I got the binary and the key.

But Pyxel Edit responds with "Invalid activation key".  I just redeemed this key from Humble Bundle website.

Hi Spazzles

Did you copy everything including BEGIN and END?

Humble recently changed the way the redeemed keys work, so you need to paste the key from Humble here: http://pyxeledit.com/get/humble.php to be able to claim the license and get the activation key.

Here is a guide to activating the program:

Hi there ... I sadly got the same problem. I bought the programm on your page and received a key from humble bundle. Sadly the key is called invalid... the link above or the guide dont help.
