For a GIS course we've provided the students with some prepared mxd files along with the linked data to work on. One of our students has a problem with an mxd. When she opens it (in ArcMap 10.7), the layers are missing and it is completely blank. Although she has the data in the correct folder no layer is listed in the table of contents. I re-sent her the file and the data folder and helped her with replacing those, but it didn't help.
The other students haven't faced that issue with the file.
I'm not sure what's going on there and how it can be fixed. Does anyone have an idea about it?
