Which window in LW do you mean? Library window I presume? Files that are Red usually mean the file is not being shared. If you right-click them & choose share they will become black. If you restart LW & they are still listed in the library window & still red, then they are still there just not being shared.

Which folder are they listed in in the Library window? When you say you loaded them onto the computer, do you mean to share, or you started downloading them?
