Purchasing a version 1.x license comes with unlimited free updates for that major version.
This means you will get 1.1 to 1.9 for free with no extra cost at all.
When version 2.0 is released, your version 1.x license entitles you to at least 50%+ off the upgrade price of version 2. You don't have to upgrade though. Use your version for as long as you want. It will never expire. doogiePIM is currently on version 1.1 for over a year now, so it will be quite a while before version 2 comes out.
After your payment has been cleared, you will be sent a special email message with a license key that you enter directly into your installed version of doogiePIM. No other download is required.
The email message with details of your purchase should arrive within a few minutes after your payment is cleared.
