The extension manager is up to date. I have removed and re-installed the extension. I thought that problem might lie with shared files. ( I'm an Adobe Cloud subscriber) I uninstalled DW CC. After uninstalling DW CC i removed the extension and re-installed it. I rebooted the PC after all of these actions. I am still get the same msg when I try to use CS Menu writer. It happens when I try to add a dynamic link,up until that time the extension works well. Attached is the error msg I receive.
