Hi Nicholas,

Thanks for reporting this problem. The problem is that the session file was written by a newer version of ChimeraX than the one you're using. You need to upgrade your ChimeraX in order to open this session. Also, a newer version of ChimeraX would have given a more understandable error message. :-)
