Yes, a lot of the search sites are now updated/linked to Limewire 2.6, even though the Google index thinks it's taking you to 2.4.

Without having the exact link handy, all I can say is that I experienced the exact same problem, persevered for about 60 more seconds with my search criteria and FOUND Limewire 2.4.4. And it WORKS fine where 2.5 and 2.6 fail to connect.

Keep looking. It's there.
