Premiere Pro Not Importing Any Files

Hi,
I'm not sure what's going on, but PP will not import any files whatsoever.  I updated PP two days ago, and my iOS a week or two ago.  I've cleared the cache, deleted all backup files I no longer need, and even done a clean sweep of old files on my computer.  I've tried importing less files (5 clips compared to the 100 I tried the first time) and I've restarted my computer as well. 
PP worked 2 days ago when I put a film together, so I'm not sure what's going on.  I can't cancel the import, because the little beach ball is just wildly spinning.  I've forced PP to quit 4 times, tried to start a new project as well as open the one I started first (though it doesn't matter, there's absolutely nothing in either file).  I've been searching the internet for a the last four or five hours and I'm coming up empty-handed.  Anyone here have any ideas on what I can do to get these imports?
