Hello,
for issues related to Dreamweaver you can post in the Dreamweaver forums, which are found here (http://forums.adobe.com/community/dreamweaver).
Unfortunately I can not help you debug the Dreamweaver file permissions issue since this is the Business Catalyst forum. We offer an unified hosting platform for creating online businesses together with a FTP/SFTP server that is used by Dreamweaver and other FTP/SFTP client applications, but we don't have access to Dreamweaver's code base.
Best regards,
Iulian Radu.
