When I open ADE, I get a message that I need to update it. When I click on the update button, it causes DW-CS4 to start and that goes nowhere. (I also have DW-CS5 installed on this machine but that doesn't seem to get the wakeup call that ADE is making.)
I had a bright idea to delete ADE which I did with AppZapper and try to install fresh. Unfortunately I seem to be getting a download error so I cannot continue with that approach.
I'm on a Mac, OS X.6.5, Intel, and not sure what else to offer/provide here.
