Thanks for the screenshot of the error.
- What version do you have installed? Get Info on the Pro Tools app in Applications.
- What version did you create this Session with?
I see you have
Pro Tools First (license activated to a MacBook Pro) and a
Pro Tools Ultimate Trial (license activated to iLok Cloud). The latter will require an internet connection (see
avid.secure.force.com/pkb/articles/faq/iLok-Cloud-FAQ) so to work offline you'd need to
Close Cloud Session (in iLok License Manager) and activate the
Pro Tools Ultimate license to an iLok. Alternatively, you could run Pro Tools First (launch Pro Tools First and then open a Project, or open a Session if you have an Avid Cloud plan).
