What happens when you add the torrent to Vuze? Does it show the percentage done and if not, have you tried force checking the torrent?

If it says 0% done, are you sure you are pointing it to Limewire's primary torrent folder, where the already downloaded data for the torrent is located?

BTW if Vuze says "Error: Path\XXXXX.XXX file is corrupt" X being some file in whatever torrent you are downloading, just delete that particular file and try force checking again.

If none of the above, what does the error say? (without specific file names)
