I am getting this same error - it is very frustrating, as I am trying to troubleshoot why a drop down is not populating properly, and this keeps poping up.
If this many users are getting this error (it is seen frequently) may I suggest that it is likely a bug, either within Dreamweaver (I am on CS4) or within the WA Extensions - and that it needs to be solved.
I am tired of deleting my configuration and cache files! :(
Thanks,
Andrew
