It doesn't save /what/ file?

Are you talking about a file that you are downloading? Or LimeWire itself? I suppose you could be talking about the .dat file? Or hashing cache?

In short - I haven't the foggiest idea what you are on about - would you like to try again - being a little more specific about what you think your problem is?

If you are reporting a bug - you really need to include a *lot* of information so that the circumstances in which it arises can be tracked down.
