I have a couple of parts where an error appears saying future version. Strangely my colleague can open them?
What version is your colleague on? Are you sure you are running SW2018?
Are you running the student version 2017/2018? Are you possibly in 2018 pre-release, or a beta version?
I remember some people reporting a similar issue a few years ago. I did a quick search, and of the few that got responses the best answer was from Shaodun Lin at future version where he suggested sending the file to the users VAR. You might try contacting them, or doing a more thorough search.
