To the last person who posted, are you also seeing the number of search results go up (the number in the tab for that search), but without any results actually showing up? (This would mean that the results are coming in, but they're just not appearing).

If so, are you also using 2.4.x (some 2.4 version)? You can see the version number in the Help>>About window, or in the LimeWire>>Preferences... window under OSX.

Thanks.
