Works fine for me.
My proceedure was to uninstall DB 1.06
Delete the WinFileCache
Start Dreamweaver
Close Dreamweaver
Delete the WinFileCache
Install DB 1.07
Start Dreamweaver
I do the same procedure every time I install a new or update a WA extension.
This is on a Windows 7 system (I realise you're on a MAC) with DW CS6
