Sony Digital Paper

Hi,

In order to sync with the site, my device needs the following info:

Server
Port
Login Name
Password
Sync Folder
Destination Folder

I've therefore entered:
Server: https://webdav.cloudme.com/cbrzezicki
Port: 443 (I also tried 80)
Login Name: cbrzezicki
Password: (my account password)
Sync Folder: /
Destination Folder: (left blank)

This doesn't seem to work. Can anyone point out what I'm doing wrong?

Thanks
