Sync Center does not find ANYTHING to Sync with.

I do not know what is going on. I have two computers, One desktop, One
laptop. Desktop is running Ultimate, laptop is running Home Premium. Office
2007 Professional is installed on both machines yet neither machine finds
Office.

I have an USB 2.0 External Hard-Drive, and two USB 2.0 Thumb-drives. They
are detected by Windows, and are accessable no problem via Windows Explorer,
yet, still, they do not show up in Sync Center.

I have the laptop and desktop on a home network, they are both visible in
the Network Center and able to connect to eachother, yet, they do not show up
in Sync Center.

I try to set up sync partnerships, and on both machines, it says there is no
available partnerships to create. What am I doing wrong? I use SyncToy atm
but I would absolutley love to get Sync Center to work!

Thanks for your time,
