I can't see my photos on my iPad mini from Windows 8

Up until recently, I've been able to download the photos and videos off of my iPad mini onto my Windows 8 box. However, the last time I plugged it into the computer, Windows updated the driver that it uses to get at the iPad's files, and now all I see in the Explorer window is an empty Internal Files folder. How do I get at the photos and videos from my PC? I might add that they're all in the camera roll, so according to this answer to another question, I should be able to see them.
