"Undo" a Killed Download?

[LAN_Drover]

This morning, when I meant to hit the "Find Sources" button, I inadvertently hit the "Kill download" button instead, which is right next to the one I meant to hit...thus killing all (100+) downloads that I had In Progress.

Is there a way of "undoing" that delete action? I see that some, but not all, of the incomplete files are still in the "Incomplete" folder though.

1) Is there a way to recover the ones that AREN'T showing up there?
AND
2) Is there a way to Resume those aciidentally Killed files?

Thanks in advance for your advice.
