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.
If you installed it no problem and can see it in the menu item, I suppose Extension Manager has done its work well. You can ask the author's help.
