This update is required to avoid potential data loss.
Note: The same important fixes in the Pro Tools 7.3.1 updates link are also included in the Pro Tools 7.3.1cs1 and higher updates, available from the
Pro Tools CS Updates page in the Support section Quick Links. Pro Tools 7.3 users can skip the Pro Tools 7.3.1 update and go directly to the latest Pro Tools 7.3.1 "CS" release if they choose, without having to install the 7.3.1 updates.
