I just paid for a registered version of Terragen 0.9 via Paypal
I did not get any redirect to a download page for the registered version or any notification of how to get my version 'registered'
What's the normal procedure then?
You should receive an email from John McLusky with your key file and instructions, but it's not an automatic process so you sometimes need to wait a few hours. I will make sure you're sent this today.
Your key has been sent to you by email.
As Matt says, key generation is currently a manual process and it's normal for it to take a few hours for keys to be sent. We do aim to get keys out as quickly as possible after purchasing though.
