a little lost, i've got all these limewireOSX.zip folders on my mac's destop. i also have an incomplete folder w/ downloads.dat file in it; also there's a limewireOSX.zip.sit.si file on my desktop, the forums are a little confusing, i also put my credit card # in thinking that i was paying for 2 yrs of limewire when my friend told me it's free, i've been reading for past hour; just can't get it to work, what does gnutella mean anyway?
