My Skydrive account still lists my PC as linked, but when I start the software it acts like I'm starting it for the first time and wants me to configure it.  None of my files are syncing.

I DO NOT want to sync my 80 GB of data again.  I want to re-establish the existing link.  I do not know what happened to cause this, it's worked fine for the last year.

How can I fix it?  (Windows 7 x64 SP1)

Thanks,

Tony
