If you are not seeing the affected order in your E-junkie Transaction Log, that indicates we have not received confirmation of completed payment from PayPal, so our system has no way of knowing the order was actually placed. Please follow the troubleshooting steps here to sort out the reason for that problem:

If you do see the affected order in your E-junkie Transaction Log, that confirms we processed the order and would have issued any links/emails you have defined for the product. This help page will help you sort out why the buyer may not have received a thank-you email, or why the email they received did not contain a link to their thank-you/download page:

I notice your product is currently set up to send a thank-you email that would include a link to the buyer's download page; if a buyer does not find this email, ask them to check their Spam folder and mark the message as Not Spam if they find it there.
You also have a Common Thank-you Email which gets sent separately for every order, but you have removed the [%thankyou_link%] tag from this message template, so it will not include a link. You would probably want to just disable this message, since you only have one product which is already sending an email of its own that provides a link. To disable the Common email message, just log into Seller Admin and click Edit Preferences, uncheck the Common Thank-you Email, and click Submit to apply changes.
