I cannot open Character animator. It keeps showing up the same notification and forced quit
I saved my project version literally one hour ago, and I was trying to open the project but it keep showing up the same two notification and forced quitted. 
even though I tried to open another project it keeps opening the same project with the issue above. I have no access to any other buttons in Character animator for now.
Do I have to uninstall chacrater animator and re-download it?
