Hi again Lisa,

Yes, directory for ebooks is a full system directory, such as /home/user/ebooks.

You are right about the thank you page, you have to create it first and the ebook module will add the download link via hook_link when your transaction is completed. It can be a generic page, no special codes needed. It could be a page telling just "thank you for your purchase." I plan to pass more variables to this page later so you can show transaction details to your clients in there.

The transaction link is always of the form /url-of-thank-you-page?txnid=x&nid=y, when x is the transaction id and y is the node id assigned to your ebook. I will add an option that allows administrators to easily get this url.

You can see all transactions logged from /admin or admin/ebook/transaction.

If I'm correct you are using Paypal, right? You need to have IPN and autoreturn enabled in your Paypal account. Check that and if you don't have a Paypal Sandbox account get one, it's very useful for debugging.

Please let me know how it goes. Your feedback is very valuable to improve future versions.
