limewire 3.5.8 | mac os x 10.2.6

for no apparent reason, the downloads list is now empty - there was a whole load in there.

all the semi-downloaded files are still on my drive.

i've tried this quite a few times - searched for one of the downloads that was in the downloads list, then clicked download to re-enter it into the downloads list.

none of the attempts have successfully indicated that they are resuming - the bar is starting off on 0% again even though the largish file is the one that's being added to

? ah! how can i get it to resume from where it had got to? why did it decide to get rid of all my downloads from the list?

any help much appreciated
