My installation of Chrome also indicates the Adobe Edge CC icon as grey color.
When clicking on the icon the panel reads:
"Please start the Adobe Edge Inspect Application....."
However, the Edge Inspect application is running.
Details as follows:
Edge Inspect CC Chrome Extension: v1.0.424.1
Edge inspect Desktop Application: v1.0.372
i spent an hour with the adobe help on the phone and they could not figure it out either. Ugh....
I spent hours trying to figure out what caused this issue too. Finally figured out, Google chrome had auto updated to version 30. For those on Windows machine, browse with old_chrome.exe (residing at Program Files\Google\Chrome\Application) to get the Edge inspect working.
Hopefully whatever issue is with Chrome 30 gets resolved soon!
