Why the hell would you want to decompile the class files, when the java files themselves are already available at limewire.org?

The whole source is available there, and in it, the ads are already disabled.

But for those that like hugely complex methods to do simple stuff, there you go. Man, I always wanted to mess with opcodes instad of just downloading the source and setting showads to true and hitting compile..

Congrats though, a truly rube-goldbergian method hehe
