Plugin: Collapsible More Link – Not Working

Hi I downloaded this plugin and followed the instructions .. I made a folder in my /plugins directory called “Morelinks” and inserted the morelink quicktag file and the morelink.php file. Then in my default them I inserted collapsible_more_link.php, and just to be safe I inserted it in my current theme. Then in my post I inserted the “<!–more|inline–>” quicktag and nothing. Any suggestions? Thanks.

Also if I may note, the normal <more> plugin put “Read More” on the left side of the post and it will take you to the permalink. In this plugin it says “Show More” on the right side, but does the same function.
