Sometimes the error exists because space is entered to the right or left of the code when copying it and pasting it into the redemption field. Please be sure to double-check that first.
If you're still experiencing problems redeeming your code(s), please email our support team at support@rockethub.com with the product name and code. Make sure to include a screenshot of the “code invalid” prompt. We’ll work diligently to fix that issue.
