When you buy a full license at full price and have bought a Trial Extension or Project License within the past three months, you receive a full refund of your last purchased temporary license.
Refunds can not be combined with discounts or coupons.
Project Licenses can be activated on both Mac and Windows, but only on machine at a time. If you need to move your license during its lifespan, deactivate it to be able to reactivate it on a second computer. Full licenses do not have this limitation.
