This will happen if:

1. You don't close LW down properly before shutting down computer.
2. Your computer crashes whilst LW is still open.
3. You delete the download.dat file from the incomplete folder.
4. You revert back to a much older version.

ie: make sure LW is properly closed down before shutting down computer. Open Task manager to make sure Limewire is not listed.

BTW if this happens, you can go to LW's Library window, select the incomplete folder, select the incomplete files & press resume button. But ... they'll start at zero % no matter what their size, etc. is.

Edit: with the newer versions of LW, once the files are forced back into the Download window, they will show zero % downloaded until they start downloading again, after which they will show their previous download percentage.

Go to LW Library window, Select incomplete folder near bottom, select first file, then whilst holding down the SHIFT key, select the last one & press Resume button. This will move them all at once back into Downloads window.
