A Dreamweaver CS5 error message, The following JavaScript error(s) occured: Unable to open script file DocumentEncoding.js 9 (error 2), is popping up. This error repeats several times and Dreamweaver finally opens, then crashes. Do I need to uninstall all Web Assist extensions? If so, what is the quickest method. Extension Manager is painfully slow. I'm not able to find the documentsEncoding.js file.
