Waves Plugins suddenly stopped working with Audition

All my Waves plugins have suddenly stopped working after being fine for several months. When I refresh the effects list it says waveshell1 isn't working. I have the newest versions of both the plugins and Audition but still the same problem. I am using Windows 10 Home.

Please help! I use these plugins regularly for my work!
