been having the same problem since upgrading to 4.16 few weeks ago.
there is this one file i manage to download successfully with 4.14 few
months ago (but then deleted it), tried again recently with the newer
version of limewire but this same file has been stuck at 94% for at least three days now. I've checked with bitzi which shows no problem for this file.

i've been monitoring this forum constantly for a solution (notice other people are
having the same problem) but so far no end in sight.
