SPhinx, i have the same problem when the newest version of limewire didnt resume. I have a hunch that when we remove limewire (oldest version) the .limewire folder still there cuz it in different directory. So the newest version possible have a conflict with some codes in the oldest version .limewire but still use them, so it make think that Limewire cannot resume the file. so the only solution is to delete .limewire, then the whole setting, the perference is resetted, back to default which mean the resuming in newest version in Limewire can resume the file.

it really strange that newest limewire dont resume it until you delete your .limewire, then it should be back to normal
