I recently purchased Logos 4 Original Languages Library but am running Logos 3.0g/Libronix because of my computer's limitations. I've been watching the training videos for Logos 3 from the website and have found that I have a fundamental problem, that is, on my home page, I have options to "Study Passage" and "Study Word" but I am missing the "Study Topic" search option. Anyone have any idea why?
