did you update your cs6?
are you trying to use text frames as shown here: https://gra617.expressions.syr.edu/wp-content/uploads/2012/08/Text-Fra me-Options-Explained-%E2%80%93-InDesign-CS6.pdf
Did you create a documetn, or just a Book? A Book (with a capital B) is a collection of documents (.indd files) and doen't do more than keep them organized and synchronized. All editing is done in the individual documents.
If you are thinking book (as in a manuscript you want to create) as a single file, then you want to create a new Document.
Finally got some instructions that make sense. Okay I can get it to do stuff, but just not type text. So it is working. The getting started videos just aren't basic enough for someone whose experience is limited to Microsoft Publisher years back. I am looking for someone locally to provide basic tutoring; hope I find that before the trial runs out!
