The file hasn't got any InCopy article

Hello, 

i'm working for a restaurant, with which i made several menus using InCopy so they can update them every weeks. It was working well, but they had an electronic shutdown, and since, when they open my icma files, it's written that : the file hasn't got any InCopy article. I don't understand because the icma is working on my computer. What can i do ? 

Thank you !
