I cannot get "Store" button to show up in menu


I cannot get the "Store" button/tab to show up in main menu on my site. It shows up in an other test site's menu selection but not this one site and I am stumped. After setting up the presentation setting I have then saved and still no "Store" tab/button show up in the main horizontal menu.

It seems that when I install (or delete and reinstall MP) MarketPress, the installation is not creating the Store page and other such relevant pages to MarketPress (cart, etc).

I am replacing Cart66 lite with MarketPress as an e-commerce solution for my site: http://www.GloryKite.com

Please help.
