Pippin addressed all of the issues and Easy Digital Downloads now works perfectly. Highly recommend!
Simple, well-conceived and easy to use, BUT EDD permission and communication problems with payment processors render it useless.
The plugin is free, but priority support is paid for. However, even after purchasing support I have had no resolution - in fact, no response to my support query in 48 hours - and it appears I am not the only one.
To be fair, it looks like Pippin may be in the midst of dealing with rapid growth that is hard to handle. Regardless, it remains that EDD does not perform as advertised at this time. I hope to see this corrected in the near future.
