I did as you suggested
Greetings, thank you for the reply.
I did as you suggested including deleting the cache file but I still was getting the same error messages, but DW did load. The extensions had already be uninstalled, so I reinstalled several, including the ones that were seemingly giving me the error messages.
Now when I run DW CS4, I still get 2 error messages related to site import (see original post).
Yes, now the floater displays as well.
Any other suggestions?
