just a few more details on above problem to see if it makes anything clearer.

the exact message is rnaapp.exe is try to broadcast to 224.0.0.2

i have also noticed when i run limewire using microsoft jvm(o.s 98se) this doesent happen,but when i switch to sun java 1.4(after rebooting)this error comes up shortly after connecting.

any advice would be appreciated as i have had no problems with any previous installations.

thx in advance.
