I have recently installed the SkyDrive app on a new Windows 8 laptop and noticed that all my Office documents are now corrupted and I can't open them. PDFs and images on my SkyDrive are working fine. I get the same "corrupt file" error whether I open them from local synced folder or from skydrive.com. I guess my question is whether there is a workaround to fix this issue or if I can recover previous versions of my files.
