I have Logos Bible Software 6.14, 6.14.0.0053. I know I'm behind a version. 
I've used Logos for years and love it. Use it daily. Convinced many to use it. 1133 books in my Library.
I'm 69 going on 70 and on a diminishing income.
So I guess us bunch of oldies are in the minority and will never be able to move along in the tools created.
Sorry I don't need any more in my library. At least very rarely. But would like to enjoy the tools for study.
But I guess I'm at the end of this road.
