No. The FAQ entries tries to explain this to you. To paste the text from there:
The donation system is entirely separate from the download system, and exists for a couple of reasons:
- our Linux users generally get Ardour without payment via their distributions’ repositories.
- some people just feel like being generous
Either way, it allows people to make a simple one-time payment. It is not part of the download system, and any payment you make via the donation system does not apply to the download system. Remember that you choose to pay as little as US$1 for a download.
If you donated when you intended to pay for a download, forward the email you received from PayPal to email@example.com, and we’ll refund your payment so that you can use it at http://ardour.org/download as intended.
