CC was crashing on me too, but I did this and the problem went away.
- Deleted the Dreamweaver CC folder in /Users/Your User Name/Library/Application Support/Adobe.
- Deleted the Dreamweaver CC folder in /Users/Your User Name/Library/Preferences
- Deleted /Users/Your User Name/Library/Preferences/com.adobe.dreamweaver-13.0.plist
- Deleted/Users/Your User Name/Library/Preferences/com.adobe.dreamweaver-13.0.plist.lockfile
- Deleted/Users/Your User Name/Library/Caches/com.adobe.dreamweaver-13.0
- Restarted the computer.
- Opened Dreamweaver CC
- Set up the workspace the way I wanted it
- Saved the workspace
- Quit Dreamweaver CC
- Restarted again.
I have no idea what was important and what wasn't, but it seemed to work.
