SAM popup removal inside WP

Trying to remove annoying SAM Pro popup inside WP dashboard.
Doesn’t matter if I install latest version or delete div code, still comes back on every page in WP Admin.
Need gone as is covering key parts of the admin page.
Ad doesn’t show on live site, only in admin!
Please help.

Here’s the div code

<div id="wp-pointer-0" class="wp-pointer wp-pointer-left" 

style="position: absolute; width: 420px; top: 725.213px; 

left: 160px; z-index: 9999;"><div class="wp-pointer-

content"><h3>SAM Pro (Free Edition)</h3><div style="text-

align: center; margin: 20px 15px 0;"><a href="http://uncle-

alt="SAM Pro (Free 

Edition)"></div><p><strong>Congratulations!</strong>
