Just went to send an ebook to my Kindle using Send to Kindle for PC and a notification for a new version update popped up. Has anyone installed it yet and used it? Wondering if it's safe to install since the last time I tried an update the thing glitched and I had to uninstall and install an older version because the new version at the time was farked and I haven't updated mine since then. I'm a little terrified of updating the software and having it not work.
