Hello David,
I am glad that you did solve your problem. Please have in mind that the main reason of not receiving the theme is:
1. The email probably went to the spam folder. In case that this happened to you, please press the button "not spam" at your email service so the next time that you will receive something from grocerycrud.com it will not be marked as spam
2. The email of PayPal is different from yours.
In any case the solution is that you can login straight after the purchase to: https://www.grocerycrud.com/users/login and press the link: forgot password and you will have access to what you've been purchased straight away. If you are getting the error message "We are sorry! It seems that there is no user registered with that email address." then please send us an email at: info@grocerycrud.com with title "Bootstrap theme not received" and at the email please have the transaction that has been made with paypal so we will have as less back and forth emails as possible (e.g. I can quickly confirm with the transaction id and the time that this purchase has been done).
Regards
Johnny
