How can I make the Fixer theme to work properly?

In the last tree weeks, I have installed and re-installed the Fixer theme several times, (I have followed all the instructions and suggestions in your manual and in your support forums), but it does Not work properly:

In edit mode, the icons and elements for editing, do Not appear in the browser, if I edit the content and save it, it does Not apply the changes to the web site.

The Upfront and Fixer themes are a great idea, too bad they do not work properly.

How can I make the Fixer theme to work properly? it is URGENT for me to make it work, since I need to finish a web site that is overdue for a customer…

Hope to hear from you soon and thank you before hand.
