The latest version SR-2 and recent downloads (the last was c. 1.5 GB) has left many installations in a very unstable state, with L4 crashing, syntax searches crashing, missing Interlinear sections on popular reverse interlinears & LogosLXX, and Biblical people, places and things being greyed out.
My advice, what I'm doing now, is NOT downloading anything until we hear from Logos.
If you want to do this go to Program Settings and set Automatically Download Updates to NO. This gives warning of a download and you can REFUSE it.
