Following my previous post about issues whit SkyDrive Pro which is not able to sync content from SharePoint 2010 (, here is the solution.

Ensure that any Office processes is not running, especially groove.exe, msosync.exe, msouc.exe, winword.exe, ecel.exe, powerpnt.exe.

Then open Windows explorer and browse to C:\Users\%username%\AppData\Local\Microsoft\Office\Spw and C:\Users\%username%\AppData\Local\Microsoft\Office\15.0\OfficeFileCache to delete all their content.

Since then, SkyDrive Pro is now able to sync SharePoint 2010 content. IMPORTANT you have to reconfigure what you want to keep available offline.
