Before doing this, I had installed and configured SkyDrive successfully to run on my secondary drive (D, versus C which contains the OS).

After upgrading, my online drive is empty. 

I still have a folder on my secondary drive titled SkyDrive with all my stuff in it.

After searching around online and in the PC settings, I found an article by Microsoft Support explaining the new version of SkyDrive does not support a root directory different from default.

Not really a problem as I can easily accomodate to this. I found a new folder: C:\Users\Joachim\SkyDrive, logically the newly created directory for SkyDrive files. I move my stuff in, but nothing happens. No synchronisation, yet I'm connected to the Internet, and SkyDrive is set to sync everything.

I think SkyDrive is still set to operate out of D:\SkyDrive back from 8.0, and it's conflicting because of this. Using the application lists my files in this directory as well.

I uninstalled SkyDrive from the control panel (doesn't have much effect, as far as I can understand, SkyDrive is soldered in Windows now), switched to a local account, deleted the folder D:\SkyDrive and rebooted.

Relinked the PC to my Microsoft Account, rebooted again, and SkyDrive created the directory D:\SkyDrive once again. But nothing is synchronising.

Something to note as well, I can't connect to my PC under "PCs" in the skydrive.live.com either.

Thanks
