Rhino 7 and Grasshopper compatibility

Hi. I am a student. Currently, my Rhino is version 7 evaluation. My project partner is using Version 6. When she sent me the grasshopper file she made, and when I open it in my version 7, I can’t somehow make it work. Is it because of the compatibility issue?

The Grasshopper in V6 and V7 are the same.
Does she have any GH add-ins that you do not have?
