Sounds like it could be a virus or something. Select it from the downld window & press the Stop button. Then go to the LW Library window & select the incomplete folder & press the Explore button which will open it for you. Then close Limewire. Find the file inside the incomplete folder & send it to the recycle bin & empty it. Then re-open LW. That will be in case someone is trying to upld it at the same time which would stop you deleting it via the Library window. How large is the file? If it's less than 1 MB then it's a virus! I'd run a virus check upon your system to ensure it hasn't been affected. See WARNING: Viruses on network you should be aware of!
