You may have experienced a delay when purchasing an upgrade via PayPal this morning. Normally all orders should be processed immediately but PayPal is experiencing instant payment delays:
Live Site Status - PayPal Developer Community
To avoid ever having an order delayed be sure to allow PayPal to "redirect" you to our site after the purchase is made. It will say "Redirecting in 10 seconds" and as long as you allow that process to occur then when the Glitchless page loads it invokes a seperate notification that generally guarantees your order will be immediately processed.
If you do not have your order within 24 hours e-mail
