Hi Amy Cox , 
 You're missing the language file & folder in your package, which is probably why. 
 The language file usually adds the module to the " moduleList ", which the application uses to find whether a module exists or not. 
 It should have something like: 
 $app_list_strings [ 'moduleList' ][ 'Lev_Course_Catalog' ] = 'Lev_Course_Catalog' ; 
 Once you add the language folder try uploading the zip again, it should work.

Since the previous upload didn't have a language, that may have left incorrect data in the lang folder. Are you on Cloud or On-Premise? 
 Can you check if there is a file or folder with this name: custom/Extension/application/Ext/Language/en_us.Course_Catalog.php 
 If you don't have access to the folder, you can also try changing the $installDefs['id'] field to something else and try installing again.
