Quickfile giving no download link

Hello,

I have successfully installed Drupal 5.10 and also Quickfile-5.x-1.x-dev. I have created a quickfile pointing to my zipfile containing the pdf book to download upon successful paypal payment. Upon making a payment I am directed to my thank you page but there is no download link there, nor do I receive an email with a download link.

I only receive a confirmation email from paypal with the transaction number inside, but no link.

I dont use the sandbox and have entered a price of £0.01 for testing purposes. Am I correct in thinking I should receive a download link via email or some other means?

Thanks in advance.
