What version of LimeWire are you using?

As I understand it, you need the original source to resume downloading a file.

The current version of LimeWire will attempt to find the original source - if it cannot be found then it will start again from the beginning - but it doesn't get rid of the other download. If the original source pops up again LimeWire can switch back to continuing that download.

Obviously this isn't a perfect solution - but it will, eventually, get the file down.

A future version of LimeWire will be better at resuming downloads even without the original source.
