Is your modem a USB model? That might be related to the issue. After opening LW wait 10 to 20 mins before using. Let it settle down 1st. Also 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.
