How to change the 'Add Album' label to 'Add Project'

Hi there I’m trying to update the navigation labels in rtMedia for when a user is creating a new Album and uploading content. I’d like the Add Album menu item to read Add Project. I have tried setting new defined terms in wp-config.php as discussed here: http://docs.rtcamp.com/rtmedia/developers/rtmedia-defined-constants.html but unfortunately that doesn’t seem to update the navigation menus as shown here: http://imgur.com/aAeP6Nh

Any help on this topic would be appreciated. Thanks!
