When you 1st open LW all the incomplete files will be queued. Then one by one they will try to connect/find an immediate source to downld from. The more incomplete files you have the longer the files will be queued. QUEUED = LW is too busy to handle those files. So after opening, wait 5 or 10 mins before using.
