Here's some pointers for optimising LW & maximising your uplds & dwnlds: A well set-up LW can start to continue its dwnlding after it's settled down perhaps 2 out of 3 times you open LW. 
Optimising LW & Maximising Uplds & Dwnlds A  (1st post only) & also 
Part B which is even better  & last & least are 
search & dwnld  hints. 
Give LW time to settle down after opening. Try not to resume too many files at one time otherwise it may play havoc with LW's connection quality & result in queuing of files for much, much longer than normal. Preferable to manually search & find new sources.
