Hi WW I hope you are well and many congratulations on the Mods position. Well deserved!
Just to clarify a bit. If a file cannot connect it will show Needs More Sources, and in my experience, you need to activate Find Sources, manually,and only after the coundown has finished, will the Awaiting Sources message appear. Then you can press Resume, but i seldom see that do anything useful.
One thing i didn't mention, which does help a lot, was that re-searching rather than resuming, the files awaiting sources will often trigger them into downloading as Limewire seems to search better with the manual push.
