navigami

Downloaded onto blackberry 8330 fine and dandy, but the icon does not appear on the screen, so I have no way of starting Navigami. It does show up in the apps folder under the tool icon but I do not have the option of starting it from there. Any ideas on what to do next?

ps : it did go thru the installation and reboot , plus I have turned it off a couple of times and still no luck on the navigami icon showing up
