I purchased a Windows 8 PC last May. Since then I have added many files  and folders to the Skydrive folder, none of which have been sync'd t0 Skydrive. When I add a new file or folder, it appears that it is being sync'd, and ultimately a checkmark appears by the file which I presume means that the sync has been completed. However, Skydrive does not have the file. All of the files added prior to May are in my Skydrive as expected. An error code is never issued.

The Skydrive version on my PC is 17.0.2015.0811

PS. I was using Skydrive before I bought the Windows 8 PC last May. Is it possible that I now have a second Skydrive as a result of the new PC? If so how do I access the new one or how do I  combine them?

Thank you.
