Greetings,

I'm trying opening learner server file from Roadway Modeling and design fundamental path from USING AND EDITING TEMPLATES SECTION (Corridor London Rd) which is 2022 version file in ORD 2021 Release 2 (10.10.20.078) . It opens but a pop window asking OK to open a read only file and close to close the action appears. Following OK opens it but it isn't editable. What steps will allow me to further work and perform modifications on it  or how can I convert it into a compatible version without loss of any data unlike in the downgrade civil tools option?
