I just upgraded to Windows 8.1 on my laptop, and now all of my SkyDrive photos and videos on my PC app are gone. I have the SkyDrive app on my phone and can still access the photos and videos from there, but they just completely disappeared from my computer! I tried reading other questions and replies on this, and even tried going to SkyDrive.com, but so far nothing. I'm hoping someone here could help me with this! Thank you in advance.
