Auto-update feature not working

I'm using JSwat 1.6.0 with JVM 1.6.0-b105, and have a question about the 
auto-update feature.  When I do:

   Tools -> Update Center -> Next

I get the error message:

   No Update Center Service Registered or Enabled

   To check the web for available updates and new modules you should go to
   Tools -> Options -> Advanced Options -> IDE Configuration -> System ->
   Autoupdate Types, add the appropriate update center service and enable 
it.

Unfortunately, I can only do:

   Tools -> Options -> ...

There's no "Advanced Options", so I'm stuck there.  However, this *does* 
exist:

   Tools -> Options -> IDE Configuration -> System -> Update Center

But even then, there's really not much that looks like it'll enable
autoupdate.  I see:

   Ask Before Check            (checked)
   Last Check                  (blank)
   Show Negative Results       (checked)
   Check Period                "Every Week"

I'm at a loss -- how do I enable the auto-update feature?

Thanks!
Pete
