Alright, I just did some testing on my iPhone, and everything worked fine with the transaction. So, there aren't any server problems at the moment. It's a shame… I wish I could see what was happening on your device. I'll have to look through our server logs to see if I see anything relevant there…  But in any case if you haven't done so already, please forward the purchase confirmation email you received from Apple to support@eventide.com together with your Eventide user name, and we'll take care of it for you.
