We're sorry your code is giving you a hard time.
Sometimes the error exists because a space is entered to the right or left of the code when copying it and pasting it into the redemption field. Be sure to double-check that first!
If you're still experiencing problems redeeming your code(s), please email the Partner’s support team with the product name and code. (You can always find this information through the "Products" page of your AppSumo account). Make sure to include a screenshot of the “code invalid” prompt. Our Partners will work diligently to get to the bottom of the issue!
