FIXED!

This, plus a restart, actually worked for me (knock on wood).

Delete the WinFileCache-7A9586CB.dat, MacFileCache-BFE7CE2E.dat, or
FileCache.dat file from the Dreamweaver user configuration folder. It is
recommended to delete the FileCache.dat file if you are experiencing a
JavaScript error related to "dwscripts" or if you are receiving a "translators
were not loaded" error message. The string of characters after "FileCache-" may
differ on your machine. The location of the FileCache.dat file depends your
operating system and your version of Dreamweaver. Note that on Windows, the
Application Data and AppData folders are hidden by default, so verify that your
Windows Explorer folder options are set to View Hidden Folders.
