Your own files will not show up in your own searches

To see what you upload use the monitor tab (next to search tab). If it is not there then press View>Show/Hide>Monitor

Also got to Tools>Options>Uploads and uncheck the box that says automatically clear completed uploads. Then press Apply and OK

When you close Limewire you lose records of uploads (for security reasons I think)

Also make sure that you haven't got uploadslots at zero

Tools>Options>Uploads>Slots How many depends on your Up speed (at least 5 KB per slot. Preferably more)

Do you have a brick wall in front of the globe in Limewire ?
