I changed my PC
I changed my PC and i wanted to install PyxelEdit, but I cant use it, because my Key is blocked (or something else).
Is there a possibility to change the Key to install it on my new PC?
Sure, that shouldn't be a problem. It could be that you are using the key from the link on Humble directly. If so you need to click that link first to get to your page on pyxeledit.com where you can find the right activation key.
I needed a while till I found it,
