Try updating to the beta http://www.limewire.com/english/content/beta.shtml
At least the beta will or should resume from where the file was at. So it should have resumed at 98%. BTW if it was a video then at 98% it might have only missed out on the credits at the end. That's if of course the missing 2% are from the end of the file.

AFAIK if LW detects any form of corruption for a file & you had previously set it to cancel such downloads & "always use this answer" then that's why you get the aborted downloads. I guess the question is why your LW is detecting corruptions. It could be anything from interference from an AV program or similar utility, firewall, line drop outs, an old modem/router that's dropping packets/not parsing properly, you've used the describe function which gives the file a different description to the original hash you downloaded, you've used VLC player to preview the file & allowed it to "fix" the file which can also lead to problems, etc.

Reverting popups to default will at least give you the opportunity to decide whether to continue the downloads rather than them self-aborting. LW's menu bar, Tools>Options>View>Popups. Corruptions detected are when the file download(ed/ing) doesn't agree with the original hash of the file you downloaded. This may be a very minor detail & not necessarily a major corruption of the file data itself.
