Woof.

Theme? Don't know. What's your OS version, and which version of LW.

Movies? I'm lucky if I can find one that will download in less than a few days, since the people sharing their files might be using their computers for their own purposes and not sharing their files whenever I happen to need one. Cheeky devils!

Hosts try to keep lists of where files can be found to save search times, but those lists are not up-to-the-minute (I've read of some being weeks old if the host hasn't run Limewire for a while). Command click the search results to search for more locations of the file, and maybe you'll hit a host with more updated lists.
Your searches will not update on their own because that would hurt everyone.

btw--anyone who posts here does so voluntarily. Limewire Pro does offer some email support, but I've read the person who answers doesn't like rude requests.

Cheers--post back with more details and lots of good people are often willing to help.
