Some hints:
* After opening LW wait 10 to 20 mins or longer before using. Let it settle down 1st.
* Don't downld too many files at once.
* See this:
To continue files downlding (click on link) & take care which files you choose to downld.
* 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.
