Skydrive Not syncing in Windows 7 with 30Gb folder

Hello.

I have been waiting for about two weeks Skydrive to Sync. The last time I saw the Skydrive notification area, it said 16 Gb of 30Gb, more or less, and for 2 days it stayed the same. I reboot the computer so Skydrive restart looking for changes but since I did that, the message is always the same "Processing Changes", without any additional information.

My Internet connection is very stable, it's a working computer and it's always connected by cable to a wide bandwith network.

¿How can I get some more information about what's causing problems?

I can see log files but they are useless for me.

Thanks in advance.
