I've added numerous Project7 extensions to Dreamweaver, one as recently as March 15. Now, all of the sudden, Extension Manager does not list DW, and I get the message "EM requires DW version 6 or greater". I'm running the latest version of DW2014.1 and EM version 22.214.171.124 with basically the same hardware/software configuration as I did on March 15.
Most online suggestions recommend starting EM with DW already running. Didn't help. Need more suggestions.
