Changing Title of Storyline 360 Web Published Files

I have published a number of Storyline 360 courses for web deployment (HTML5) and there has been a small change to the title. Rather than going to every course, changing the title, and republishing, is there a way to edit the code to change the title in the player. I found a post where you can edit frame.xml and meta.xml to change the title. I found where the title in these files and changed them but the old title is still there. Any idea what I am doing wrong? Thanks!
