inner radius missing from the initialize pallet while using primitives

My primitives are missing .So is the tool menu where they are usually located . Is there a way to reload them ? I can get to the main tool menu where the Polymesh3D tools are but not the primitives . I looked in the tools folder and there are no primitives there . Did a search and found no primitives anywhere . Is there a primitive tool file I can download ?
Nevermind found the Primitives . I still have no idea where they are hidden in the file folders . So when I found them I made copies in a folder I can actually find . Earlier I had done a search through my whole computer by their file name and came up with nothing . Used two file search engines neither came up with the files . Even though I had the exact file names . I finally found them listed in that scrolling slider list under the Lightbox/Tools button . I had looked there several times before and didn’t see any of them there . But for some reason they suddenly appeared there .So I loaded each one and put a copy of them in another folder . So I can actually find them . Once I loaded one the screen where they were supposed to be finally showed all of them . Never ran into this issue before . But I rarely have used them . Because I never realized how important they are . Now I do .
