Hi Again. :)
I'm trying out the Drupal 5 Version and everything is working great all the way to the final step.
Upon setting up a transaction to test, the download link was emailed to me. When I went to the link "Download your quickfile" it always fails and returns with the Error Downloading File page I set up. I've tried everything to debug this that I can think of, and the results are always the same.

I have no issue setting up the quickfile, and the file I'm using is always found during the setup process.

Do you have any suggestions?
