Highslide installation problems

Hello,

I have a question about my Highslide plug-in. I recently installed Highslide for my website’s gallery, and I have highslide.js as well as the highslide plugin activated. However, when going to edit the files, I am told that the highslide.js file of the plug-in is not activated. How do I activate this file? The actual wordpress plug-in is activated, just not this file.

Thank you for any help you can give me!
