When I click to open Logos5 I am presented with a box saying an Update is ready to be installed. So I click to do the Update and after going through some of its preparation I finally get this box

I cannot figure out what the program wants. I have checked the file logos.exe.mui and even gave "everyone" access to it, but nothing seems to work. I can Cancel and Logos5 goes ahead and loads just fine. The only thing is that I now notice I have lost about 100 books from my library. Could there be a connection?
Not sure why the program wants a Logos4 Folder, anyone have any ideas. Thanks for any help in resolving this.
Oh, also, from inside Logos5 when I check for Updates I get the response that there are no updates available.
My version is Logos Bible Software 5.0 SR-4 (5.0.0.1835)
