"Based on the category you selected, we understand that you are trying to recover a lost, missing, or otherwise inaccessible purchase you've made with Humble Bundle. To better enable us to help you, please include any relevant details about your order which you can provide, if you have not done so already.

One particularly useful piece of information is the 13-character transaction ID included on the receipt for your order which begins with the letter X or the letter A. If you can locate this code, please provide it in a reply if you have not given it to us in your initial request. The transaction ID is a particularly useful bit of information because it allows us to locate orders even when they are not associated with your account or email address."
