Trying to use Feature Works on a STEP. file and a IGES. files, and I can click on Feature Works, and Recognize feature and Options, but then nothing happens. Am I missing something?

I'm trying to use Feature Works to recognize features on either a STEP or IGES File, and I've enabled the Feature Works add in, and the selection isn't grayed out, but when I select Recognize feature, or Options, nothing is happening. Am I missing something easy?
