I purchased Logos 4 Leaders base package a couple months back. I've really been enjoying the software. However, I was not aware that there was no way to upgrade from the Leaders to Language package. I really need to get the language tools that the language package comes with but I really don't have the additional $300 for the Silver Scholars at the moment. I saw some add-in's on the Logos webpage but I'm not sure they work with the Logos 4 package. Does anyone know a way I can get the additional tools? (Sentence diagramming, morph river, etc.)
