The first time I clicked on the link in your message I found a bunch 
of dated folders. When I tried copying either the 2011 folder or 
individual items inside it to my desktop, I got an error message:

"The Finder cannot complete the operation because some data 
in...could not be read or written. (Error code -36)."

Then I tried backing out and trying again. This time I got the FTP 
user name and password dialog. I entered "Guest" for user name and no 
password. But I got the error:

"The user name or password you entered is not valid. Please try again."

I got the same results from a Windows machine.

Thanks for your help.
