Are you sure it doesn't say that only search results with the symbol are official
communications? Communications are messages that tell you to update LW to the latest version or some other information you might need to know. It doesn't have anything to do with the files your d/loading.
You should be able to d/load the files in your search results. Have you tried? If so, what happened? Did they go to the d/load window? Did they go to "needs more sources"?
