This is a software upgrade Renewal Plan for existing owners of Avid HD or Ultimate software who currently own an existing upgrade and support plan. If your Pro Tools plan is about to expire, this Avid Annual Upgrade and Support Plan lets you renew it. This plan provides you with a year of software updates as soon as they're released, and one year of top-tier support from Avid, ensuring that your system remains current with up-to-the-minute releases and upgrades. This Avid Annual Upgrade Plan is not a subscription. If you choose not to renew this plan when it expires, the Pro Tools software and the upgrades you've received are yours to keep.
