1. Use points 1 & 2 here:
Fixes for Limewire ie: reinstall Java using the "Offline" installer, & delete your LW preferences folder.

3. Don't rush into using LW after you open it. Let it settle for 10-20 mins before using. Also, don't use the Resume/Find Sources on all your files if you use it at all, this WILL have the effect of using up all your computer's resources! If you use this function, use it on only one to 3 files at once. Also don't downld too many files at one time.
