Your post is hard to understand exactly, but Are you doing this in the search window? If you get the number zero or no number, preceded by the ip number ... The page will stay blank, or the screen mayl imediately revert to what it was before if the host can not be browsed. If you get a number after the ip number, that number of results should show up in the search window.
The ip number will typically be something like xx.xxx.xx.xx.
Have a look at the user guide, link below, probably in the searching section, but the whole thing is a good intro. to Limewire. If you sill have problems please be more specific as to exactly what you are doing and what happens when you do it. Try browsing a few hosts, because the first one you try may nor work
