If you need to reset your v4 templates, you will need to download the attached file, unzip it, and place the contents into your templates folder.
The templates are located in your My Shout\V4\Plugins\Cue Templates folder. You can simply delete the files in that folder and replace them with these original templates.
Note: These templates are for version 4 and will not work with version 3 of MediaShout.
