Cost to Upgrade?

What is the cost to upgrade to the latest Standard version of OmniFocus? When I click the Upgrade Existing License link and then click on OmniFocus 2, when I enter my license owner name and license key, it says “This license appears to be already upgraded.” Does this mean I’m not eligible for an upgrade even though I’ve owned a previous version of OmniFocus?

Thanks in advance for your response.

You shouldn’t receive that message unless your OmniFocus license has already been upgraded, but the quickest way to get this sorted out is to email or call +1 800-315-6664.
