Try some of these:
* After opening LW wait 10 to 20 mins or longer before using. Let it settle down 1st.
* Go to LW's menu Tools>Options>Speed & tick disable Ultrapeer Cap. & press apply button.
* Set both uplds & downlds to autoclear.
* Close all LW windows you don't need open at that time. (menu View>Hide ...)
* Reduce uplds speeds to about 70-80% or more (if you're using dial up then reduce to minimum.) Reduce downlds to 80 or 90%.
* Don't downld too many files simultaneously.
* Don't use the Resume button on all incomplete files. This can have side-fx such as affect LW's connection quality. May queue your files for much much longer. This will also stress LW & your comp. If you use Resume/Find sources then just apply it to a couple or so at one time.
