Locate the file on your PC, NOT in Limewire, if its in a shared folder or the like then move ALL the other items in that folder to a new folder (if your folder is "my videos" for example make a new folder "my videos 2") leave the rogue file in that folder, click up on the folder and delete it. This should take your rogue video to the recycle bin, you can then re-name your folder by taking the "2" off
