Did you click on the incomplete folder in the Library window? If there's an arrow there you may need to click on it.
Did you select the incomplete folder & press Explore (that will open the folder up, else the parent directory folder) ?

Did you update your LW & find some files missing? It might be because LW now stores them in a different location; http://www.gnutellaforums.com/window...downloads.html

If your incomplete files are older than a certain age then LW may ignore them (removed them from its download history records), see http://www.gnutellaforums.com/downlo...tml#post326274
