Russell Brown's Flypaper Textures Pro package for CS6?

I have Creative Cloud and have installed the Pro version of Rusell Brown's Flypaper Texture package.  When I try to use it by going to Window-Extensions- all if get is the installed extension.  When I click on it, it just installs it again.  How do I actually access it to use it now that I have it installed.

Thanks,
