[Plugin: wordTube] How do I limit access to Manage Media Center?

I have some contributors to my website, but they have access to the WordTube Media Center.. and I do not want them to have access. In other words, I only want the admins to have access to the Media Center. I have tried to change the variabel is_admin() in the plugin.. but can’t figure it out.

Can someone please tell me how to prevent everyone from accessing the wordtube media library. It’s the only plugin where I have this problem.

Thanks!
