Hi there! I've been using Calibre for years now, and I totally love it. I added a couple of new books to my library last night, then closed the app. Just now I plugged my Kindle Paperwhite into my computer and tried to open the app, but was greeted with the following error:

calibre, version 2.15.0
ERROR: Unhandled exception: <b>IOError</b>:[Errno 22] invalid mode ('w') or filename: u'/Volumes/JetDrive/Google JetDrive/Books/Calibre Library/calibre_test_case_sensitivity.txt'

Can someone please tell me if there is a way to fix this? I'll admit I don't know what the above message means, but I'm good at following directions!

I really appreciate the help!
