The Avid Pro Tools Ultimate Perpetual License gives you the latest version of Pro Tools Ultimate plus one year of software updates and support, ensuring that your system remains current with up-to-the-minute releases and upgrades. This is not a subscription and if you choose not to renew the updates and support plan when it expires, then the Pro Tools Ultimate software and the updates you've received up to that point are yours to keep.
You have one year of updates and support with this license. After one year, if you choose to continue with the "updates and support" plan then you will need to purchase a renewal. You must monitor your Avid account to determine when your "updates and support" plan expires and purchase/activate your renewal prior to that date.To purcahse a renew click here: Avid Pro Tools Ultimate Updates and Support Plan (Renewal)
However, If you let your "updates and support" plan lapse you will have to purchase a reinstatement or continue to use the software without the updates and support. To purchase a reinstatement click here: Avid Pro Tools Ultimate Updates and Support Plan (Reinstatement)
