iTunes Audiobook missing.
I bought and downloaded an audiobook on my iPhone 4, and later synced it with iTunes on my PC. A couple of days later, I find that the audiobook is no longer on my phone for some reason. I figured it was just some glitch, and so I started up iTunes on my PC again, to see if re-syncing would help. That's when I found out it was no longer on iTunes either. The folder that iTunes keeps audiobooks under on my PC still has the audiobook in it, but iTunes doesn't seem to be picking it up. Apparently you cannot re-download audiobooks either, so the £8.95 I spent is now wasted. I heard that Apple can do a 1-time reset or something? How would I do that?
iPhone 4, iOS 7.1.2
