Quote - I'm wondering now if I caused problems with the P7 runtime by copying and pasting it from a backup drive

I don't think that's the problem.  I use an external HD (or a 64Gb flash drive for the laptops, or more recently, an express card SSD) on a regular basis to copy my library to all of my computers so as to keep their repertoires uniform.  I also used this method to establish a downloads/runtime library for P8 (in the shared docs) on each computer.  I have P7, Pro, and P8 all using the same library without any problem.
