hi there @Armi2k5! sorry to hear the process is not working as expected… since the gift key is working, it would seem (at least) Humble Bundle does have a record of your transaction… so, thats promising!
i would suggest reaching out to Humble Bundle directly via contact@humblebundle.com… explain the situation, and im sure they can get you squared away… if you have any transaction details (emails from when you pledged), that will be helpful as well…
if you have any other questions about the process, you could take a look at this thread as well…
good luck, and keep us posted…
