@misslivvy: Marcus would be able to give you better advice but I noticed that you still haven’t got your text changed so this might be helpful for now:
Go to line 35 in /wp-content/plugins/events-manager/templates/forms/event-editor.php and change the text in following line:
<?php _e ( 'The event name. Example: Birthday party', 'dbem' )?>
To your desired Text.
Hope it helps.
NOTE: You might have to change the text again when plugin is updated.
