I paid today, at 02:34:51 -0700 according to my paypal notice. I have instant SMS notification by my bank of any transactions, and it did indeed notify me of the transaction coming off my account.
It is now 09:13:00 -0700 I think (14:13 GMT-2), almost 7 hours later, and I still don't have my license key.
Can you please have a look? I'd like to start using the software I paid for.
