This is b/c you're dwnlding from a different source. Moving the file out of the dwnld folder may have affected LW's downloads.dat & .bak files. Have a look in your LW Library window & see what size your file is. You can try deleting the file from the dnld window (on search window) & going to lib wind & press force resume from the incomplete folder. Howver doing this risks the file starting from zero since the downloads.dat file has possibly been ammended.

What 'I' would do is (1) I would go to Library window & delete any listing of that item that is obviously less than 55% from the incomplete folder - you'll probably have more that one item in the incomplete folder listed! But make sure you delete the right one! Careful! (2) Then I would delete the listing from the dwnld pane of the search window, (3) then search for this item & reselect it to dwnld. If it continues at anything less than 55%, then I would delete it again from the dwnld pane & select another from the search results. I would continually do this until it works, also trying another search. If still no success, go to LW's menu & View-Show/Hide-Search & temporarily untick MagnetMix. Now try searching again (doing this may/not make a difference.)
