First time here.....For several years I have run a small MAILWASHER. Yesterday I started getting the attached error - and cannot even get rid of the error message, having to use Task Manager to close the application. Now, I know nothing about the file/error or how to correct it. I am not a coder.....I tried re-installing but nothing changed. How do I correct this?: Line: 16 Char: 4512 Error: Object doesn't support this action Code: 0 URL: https://cdnjs.cloudflare.com/ajax/libs/gsap/latest/TweenMax.min.js Tried to attach a screen pic but just got error 301......
