Error Building Admin Menu

I am trying to install Community Builder and it all installs fine with one exception. I am getting the error message “Error building Admin Menu” right above the “Installation was successful” bar. When I go to the components drop down menu in the back end there is no Community Builder tab. I heard that there may be something in the joomla/installer code that needs changing as it is not assigning a menu id to Community Builder but I don’t know much about this. I did purchase a template that had a dump file which gave new josh_ files. They are called hero_ files instead and are like hero_menu etc. I am wondering if I need to delete one of these files or if the fix is in the joomla installer code itself.
some ideas?
