The standard wait time is seconds after purchasing. You should definitely contact Saberfont.com about this - the folks there are very responsive.
That's odd then if the email is supposed to be that fast, as the shortest wait period I've experienced since the update to the web site has been about a day.
Forgive me if this is obvious but have you checked junk mail as well as your in box
Although the email from the previous purchase did not go to the junk/spam folder, that was the first place I checked after it had been 24 hours.
Did you create an account? You can download it through there as well
It was as spur of the moment purchase, and assumed I was just under a guest account. It was not until I got to work this morning that I realized my work computer had kept me signed into my account, and the download option has expired.
I emailed saberfont yesterday, and now waiting for a reply.
