I've been going through the same verify-and-repeat-downloading from around 96 percent. This is my second attempt at downloading the 525 meg file! But oddly enough, I made a copy of the file from the Incomplete folder (an MPG file that I renamed) and had Quicktime open it just fine. YET, if I close Limewire and click on the original "incompleted" mpg file (the one with all the numbers preceding the title), Quicktime will not open it.

So, I have *two* files -- a seemingly good copy that Quicktime will open -- and the same one in Limewire's "Incomplete" folder that you say is corrupt (and that Limewire tries to re-download)...
