Yes, this was part of the problem.
Thanks for that. Didn't know about this.
However, still having problem with the download page.
Is it necessary to have the customer complete a registration or signup page in order for the data to be "transferred" or whatever to the download page?
Or can it come right from the checkout page?
I was going shopping cart ... confirm (skipped checkout but uploaded, just not used) ... to paypal ... and hopefully to download page.
