File downloading well but then going backwards!

[Clem19]

Hello! I've been using Limewire for a while now but still haven't get this:

A video file dowloads well and is, for exemple at 75%, but for no reason it goes back at 10% or less.

Usually, I notice that problem when I start Limewire, even when I stopped it without problems.

So could someone please tell me where it comes from, and how to fix it?

Because when I go to the "Incomplete" folder, the file size hasn't changed and if played, will go until the 75%!

If tried deleting the download but when I put it back, Limewire still says 10%.

So please help me, 'cause when it happens to old files that nobody shares, it's really annoying.
