What is on offer right now is basic and version 0.0.1 has a couple of issues. No worries. Development is daily and there is a lot to come.
Activation Screen Issue
I want to be clear about the activation process. It is not an API/web service activation, no key or anything like that. It's the beginning of anti-bot security that shouldn't really apply to administrators. That screen should not be showing up right now. I will get that sorted later today. Activation is meant for subscribers and the activation process will check the subscribers customer/client status.
The idea behind that is to avoid creating all the extra customer data even when a customer is not using the WP e-Customers services. A customer may purchase on WP e-Store for example. They then download their purchase and never return. No point creating a bunch of rows in the database for that user right.
