Problem with Lifetime purchase

Hi, i have a problem with lifetime purchase
i have created a DOCUMENT in the backend. when a user buys this document, you can download it without problems.
when I update the version of the file, edit the document. In this way those who have already bought should not repay. right?

the problem is that a user can not download the update but found only the ORDER IT link. the file is published in LIFE TIME.

how can I solve this problem?

tnx (and sorry for my bad english)

Hi

1. You need to ask your customers to register for an account on your site .

2. You need to assign order to his account . If users register to your site using the same email which the email he entered on order form to purchase order, the order will be assigned to his account automatically and you won't have to assign order manually to his account.

3. You create a menu item to link to history view of Documents Seller. Users can click on this menu item to see his orders history and can download the updated version of the document without having to pay again .

Hope my explanation is clear to you !

Regards,

Tuan

tnx, i think the point 2 is the problem.
