"Import iTunes library" option cannot be selected.

When I start up Songbird for the first time, Songbird "allegedly" offers me the option to import my iTunes library. However, this feature is disabled and not clickable. Is this a vaporware feature that will be added in a future release, or what do I need to do to select this option? It does not work whether iTunes is running or not.

I have tried this multiple times, manually resetting the "first-start" flag in about:config each time since the import is apparently only offered once after installation.

Edit: If that makes a difference, I am using Windows XP.
