I'm guessing that since Limewire is a Java program that you might be seeing the symptoms of not having the Apple Java package installed. I believe this is now part of OS 9.*, but it may not have been included in version 8.6. I'm also guessing that this would be something you can download for free from Apple and has an extradinarily obscure name like MRJ 2.2.2.

Again I'm only guessing, but I'll leave it to the real Limewire developers to confirm this.
