Rhino Crashed and when I reopened I lost Grasshopper

Saved files from Grasshopper wont open, Rhino wont show Grasshopper Icon
I am on the 90 day free trial period for a class.
Is there anyway to restore?

Hi - what happens when you run the Grasshopper command?

Hey, so at first I didnt have the Grasshopper command when opening Rhino but I think I got it back. I followed one of the other FAQ answers and I have it up and running again but I lost my entire file that I was working on before the crash
