Well, you have two basic options:
 * 1) If no licensing is selected, add a default category which will include all files that require a proper categorization.
 * 2) If a user clicks the "Upload file" button yet no valid option from the licensing dropdown was selected, make a popup window appear, telling the user to select a valid option.
