I too have not been able to get the PIN number after downloading the app. I have not received an email to date either. I also ordered the FVB from them, the website said it was in stock unlike most other merchandise. I paid with PayPal, a few days later I received a email from PayPal that I got a refund from Knife Grinders for that purchase price. I can only go under the assumption that their website had not been updated and the item was out of stock because I have not received reason as of yet.
