The files 'must' still be in the incomplete folder. Unless LW 4.18 is pointing to a different download folder. The incomplete folder simply reflects what's in that folder on the hard disk drive. Go to Tools -> Options -> Saving, choose the location where you saved them before. Or check If you updated LimeWire & cannot find your Downloads

1. I am using LW Pro version 4.18.
2. When I right-click on the download as it resides in the queue I do NOT get the option bitizi lookup!
