Can you please give us a screenshot of your screen. There are two main options for importing media into the Organizer. Either you use the File>Get Photos and Videos menu or you use the larger Import button which has a similar dropdown list.
If you are not seeing either of these command prompts, and you are on a Windows machine, it is possible that you have the Windows Task bar set to auto-hide. Turn off the auto-hide option and the menus should appear as my screenshot.
There are several other methods for importing media into the Organizer but I shall await your response to see if you need further information.
