I am also having the same problem with a firewall.. I do not have a firewall.. I have checked, believe me!! Here is some info that might help in answering the big question why wont limewire work!
Ok here goes.. I run Microsoft ME, my CPU is 4.90.3000 I have 95MB of ram and I use Java 1.5.0... I hope that is all the info that you requested..OH yeah.. I also use DSL for my internet.
