I know that you're p*ssed, but no matter how much you moan about it the files wont just reappear. Normally they are left intact even if it goes back to the 7 days limit.

Is there no software to search the computer for deleted files, that you know of?
I use Windows myself so wouldn't know about any for OSX.

If you are able to find some of those deleted files, there is a good chance that you can restart them by finding the file in a search, start the download and then close Limewire.

Then take the original file and replace the new file

Note: Filenames have to match exactly. If you need to rename, then rename the old file or Limewire wont recognise it.

P.S. Losing 4 Gigs isn't that bad + many of them you probably would have a hard time finishing anyway.

P.P.S. starting an argument with the site administrator = Not a good idea
