I recently purchased a Windows Tablet from Dell and set up a Microsoft account for it.  A few days later I upgraded my PC to Windows 8 but set it up under a different Microsoft account.  The Skydrive account on the PC has several Word documents, Excel workbooks and Access databases  that I wish to access and update from the tablet.  I can open the files but they are not up to date.  How do I sync them?  I have tried examples/instructions from several sources but nothing seems to work.  Any help (as detailed as possible) would be appreciated.
