PSB file showing as if its correct but when I click on it all of my work is gone

Hello everyone, 

I need some help. Sunday, I was logged out of my adobe by another user of my account. Up until being logged out, all of my work was saved, and all of the files that were saved are still able to be accessed on my computer. Except for one large file. It shows on my computer as if my work is still in the Photoshop file, but when I click on it to view/work, nothing is there and is shows the picture below.

This is the first time where I've been logged out and my work has been saved, yet I'm still not able to access my work.

Really need some help with this. I'll attach pictures below for clarity. 

Thanks!
