SkyDrive (native to Windows *) does not sync

After hours of work, SkyDrive does not sync.

I've reinstalled it completely many times.

I've applied all known Windows updates.

I've emptied my SkyDrive multiple times and gotten all my docs in SkyDrive.

I've restarted my computer.

I've restarted SkyDrive.

I've forwarded log files to Microsoft.

I've done everything recommended by Microsoft except making changes to the registry. 

SkyDrive won't sync existing or new files.
