megami20, chillax a bit. You get what you pay for in these support forums.
What the people are doing wrong is likely just not understanding how the plugin works – or more likely not understanding how WordPress works.
If you want help though, you need to explain a bit more than “it’s not working”.
First thing everyone needs to do is check their theme to make sure it is using <?php the_excerpt() ?> instead of <?php the_content() ?> where you’re looking for excerpt text to appear. You can do this under the APPEARANCE->EDIT menu in the backend (or just edit the php files in your theme folder via FTP).
If none of that makes sense, then you need to take an hour or two and familiarize yourself with how WordPress themes work. If that all makes sense, come back and explain clearly what is and isn’t happening.
