Hello Hedy,
Dreamweaver should allow you to overwrite your site files, and according to your CNC File Manager section your index.html file is showing a last modified date of today, 09-16-2015, suggesting that the updates/changes you made were in fact published successfully.
Please verify that you have refreshed your browser by holding SHIFT+reload, or CTRL+F5 (or in some cases SHIFT+CTRL+reload or SHIFT+CTRL+R, it varies depending on the browser being used). Sometimes your browser or ISP will cache the result from a previous visit and you need to force a browser reload/refresh to view updates you make to your web pages:

If you continue experiencing issues please send an email to
Service@FutureQuest.net detailing 1) the publishing settings you currently have set in Dreamweaver, and 2) what particular error message you are receiving in Dreamweaver (if any).
