Uploading is when someone else downloads one of your files... it's a download for them (comes 'down' into their computer) & an upload for you (goes 'up' out of your computer)

I guess you're seeing no search results (no list of files after you do a search). You won't be able to search until LW's connected. For your connection issue,try the fixes in the thread below. If nothing there helps, please post back with your system details (the link below has info about which details we need)
