can't edit or remove plugin

Hello,

I installed the “Password protected” plugin on my wordpress “Volt Magazine theme”(http://themeforest.net/item/volt-magazine-editorial-wordpress-theme/1044745).

When I went to the plugin section, there is no “deactivate” or “Edit” links below the “Password Protected” line in my plugins. So I can’t seem to do anything with this plugin.

Can you please suggest how I can either make the plugin work or remove it?

thank you,
Matt
