IMHO I'm not sure why you'd bother replacing the old ones in that case. Since they will still continue from where the new ones are at. Since the downld.dat file is the record keeping file. If the old downld.dat file was completely corrupted in the 1st instance, then perhaps just doing Sleepless's 1st part of his suggestion (points 1-4.)

* Ah ... I just realised your problem ... until the files recontinue they will show zero %. But after they start downlding they will continue from where they were! So search for the files again on the network & use the 'Get more results' function & perhaps you'll get lucky & they'll restart downlding. If no luck after a persistant effort, then do Sleepless's suggestion ... at least points 1-4. But simply using the Find Sources / Resume button is NOT a greatly effective technique of finding sources. Search is the best way! You do know about the Get more results search function right? Right-click the search result tab & check the options.

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?
