I have a Windows 7 PC and a Windows 8 laptop that I use to access files on my skydrive through the Skydrive app. I have noticed recently that the files from one PC does not appear to be updating in the skydrive on the other. I have recently had to reinstall Windows 7 on the PC and wondered if that could be an issue and how do I fix it? Otherwise what other issues could be inpacting this?
