[Plugin: Email Users] Change the email sent message?

Hi all I was trying to change the message sent to users.

I edited the email-users/email-users.php but its not updating on the preview and the old text as below is being sent via email??

'mailusers_default_subject' => __('[%BLOG_NAME%] A post of interest: "%POST_TITLE%"', MAILUSERS_I18N_DOMAIN),
		// Mail User - The default body to use when using the post notification functionality
                 'mailusers_default_body' => __('<p>Hello, </p><p>I would like to bring your attention on a new post published on the blog. Details of the post follow; I hope you will find it interesting.</p><p>Best regards, </p><p>%FROM_NAME%</p><hr><p><strong>%POST_TITLE%</strong></p><p>%POST_EXCERPT%</p>
<ul>
<li>Link to the post: <a href="%POST_URL%">%POST_URL%</a></li>
<li>Link to %BLOG_NAME%: <a href="%BLOG_URL%">%BLOG_URL%</a></li>
</ul>
', MAILUSERS_I18N_DOMAIN),

/***My edited code***/

'mailusers_default_subject' => __('[%BLOG_NAME%] New Post: "%POST_TITLE%"', MAILUSERS_I18N_DOMAIN),
		// Mail User - The default body to use when using the post notification functionality
		'mailusers_default_body' => __('<p><strong>%POST_TITLE%</strong></p><p>%POST_EXCERPT%</p><ul><li>Link to the post: <a href="%POST_URL%">%POST_URL%</a></li><li>Link to %BLOG_NAME%: <a href="%BLOG_URL%">%BLOG_URL%</a></li></ul>', MAILUSERS_I18N_DOMAIN),

Any help would be much appreciated
