As you might have heard on the news by now, the Amazon Web Services (AWS) US East Coast datacenter in N. Virginia is currently experiencing significantly increased error rates:
https://status.aws.amazon.com/
Our services are hosted on AWS from the affected datacenter, so this event may affect our services as well, notably file uploads/downloads and email delivery in particular, though we're currently still assessing the extent of impact to our services. At this point, resolution is just a matter of waiting for Amazon to resolve the problem in their system, so those of you with buyers reporting download trouble can simply advise them to try their download again later tonight or tomorrow.
It appears that delivery of some emails (incl. thank-you emails and sale notification emails) may be sporadically delayed; the affected messages are simply backed-up in an outgoing mail queue, so they should ultimately get sent out as available functioning mailserver capacity allows.
If a buyer reports they did not receive their thank-you email with a link to their download page, you can first check your E-junkie Transaction Log to verify we processed their order (if it shows up there, we did), then just right-click on their Transaction ID there and copy the link, then paste that into a personal message to the buyer with advice to try downloading later due to this ongoing issue.
Thanks to everyone for your patience and understanding while we ride out this storm together, with our apologies for the inconvenience.
