OK maybe i misunderstood. Which version of LW are you using? LW 4.8.1 or one of the 4.9.x betas?

So you tried changing compatibility mode of LW to win 2k, & you tried running Java 1.4.2 instead of Java 1.5?

If you have tried those things then perhaps beta might be the way to go. http://www.limewire.com/english/content/beta.shtml or if you're a pro user you'll find a link to the pro beta on your personal downld page.

Can you give more detail about what happens & after which events? Does LW actually open up at all & if yes, does it crash & at what point?
