I just purchased cubase 13 pro (upgraded from cubase 12 pro) and after paying with paypal, I did not receive any information from steinberg in my email inbox, including the download address, license, etc. Only received an order confirmation message from paypal that the payment was successful.
I entered my email address when I made the payment, but there was nothing in my steinberg account.
Maybe your license is already in My Steinberg?
You should have been emailed a receipt and access code. Check your junk mail or maybe double check your order went through.
When payment was accepted a new web page should have opened with all the necessary details, as well as an email. Check your bank/Paypal accounts to make sure payment did go through and open a support ticket with Steinberg/FastSpring. Here, you’ll only get guesses.
