I FIGURED OUT A WORKAROUND!
After hours and hours of trying to load the library, I finally looked in the templates folder and opened up the Default14 file.  I was able to load, playback, and input all the right notes in all the right places!  I then saved the library into a different name, and loaded that library into a new and older file in 2014.  Everything worked!
Now, I have transposition issues with the files from 2011 into 2014, but I don't really need to hear that stuff back anymore.  As long as I can input into 2014 with no problems I'm happy!  I still can't load that library, though.  But it looks like I don't need to now!
But quick question... I want to make sure I save all the right things from the Default Template.  When I "save library," should I just check every box and load into my new document?  Or are there things I can remove (like midi data, and such)?
Thanks so much for your time and patience.  I appreciate all your help!
