It sounds like LW is overworked. You're over-cooking it so to speak. Ease up a bit.
1. For a start, don't do anything with LW until all the incomplete files & shared files have loaded & been accounted for. And allow LW to settle a little after that. Depending on how many files this might take 5, 10 or 20 or more minutes.
2. Don't resume everything to get them started continuing to downld. This takes a lot of energy out of LW. A lot! And is also not the most efficient way of achieving it. eg:

LW uses the majority of its resources for downlding & searching. If it's still busy doing other things such as loading files or resuming then it's energy level may become very low & affect LW's media player's effectivity/functionality.
