Getting your download again later
The link in your receipt lasts 24 hours, so if you come back to it next week it'll have expired. Don't worry, you can always pull a fresh one. There are two routes depending on whether you've got an account.
If you've got an account: 1. Log in at the login page. 2. Go to your order history and download again. It generates a brand new link every time.
As a guest, with no account: 1. Reopen the receipt email from your purchase. Opening it refreshes the link. 2. The first time you view your orders you might get a quick "verify your account" email. Click the link in it once and you're through. It's a one-off, not a hoop you'll jump every time.
Lost the receipt entirely? Reply to any email from me and I'll resend it. If you're stuck getting in at all, Still stuck? points you the right way.
Still stuck? Don't wrestle with it. Reply to any email from me, or get in touch, and a real person, me, will help you out.
