Power outage removed my project from Library

While play testing my game I had a power outage. It some how caused my project to be removed from the library. The files are all still there in my C drive but when I open the .uproject file it get the error message “Couldn’t set association for project. Check the file is writeable.”

This is almost 6 months worth of work, please help.

Crisis averted. The solution is to this if anyone has problem is to get a .uproject file from another project and replace broken one, just make sure its name exactly the same. Click on the file and it should work, unlike my countries power grid.
