I have this error notification on Windows 8.1 which says 'Files can't be uploaded because there's a problem with a file or folder'. This error followed by a file path. I have managed to take care of this erroneous folder and now that 'busy syncing symbol' on the folder is gone. So, SkyDrive is back to normal and everything is good. Unfortunately, the above error continues to remain in the SkyDrive app and the icon in File Explorer continues to have a exclamation symbol next to the SkyDrive cloud logo. In terms of functionality, SkyDrive is working fine. It is just that the error message won't go away and that exclamation symbol won't go away. It is annoying as h.ell. Before I updated to Windows 8.1, I could just quit SkyDrive desktop app and restart it. Now, I cannot do that for SkyDrive is integrated into the OS. Any suggestions would be appreciated.
