Please Help me, Grasshopper Problem

Hello, I have a HUGE problem. My final project is due this Wednesday and I cannot open my grasshopper file. It says it has to do with an error that occurred during a “read/write file”. I’ve attached a picture of the message. I have been working on this file for about a month. I need the file fixed now so I can work on my final. What should I do, who do I contact?

Oh no.
