If his problem is them starting at zero % and not getting them to continue. This is the only way to get them going again.

It's only the downloads.dat file that's corrupted, and the new files will be at zero, while the old (useless) files are partually downloaded. With the new downloads.dat file you get connections for the new files, just under a different filename (in most cases). when you switch the files (with Limewire closed off course) and change the old filenames to fit the new filenames exactly, Limewire will in most cases notice that the file is partually downloaded after the switch.

Pointman got this to work, so why shouldn't lethal?
