Java Exception in OSX.1.5 when hitting Search button

below is the java exception error message that it getting output to out.txt in my limewire directory. I also get this error msg when I run the app from the command line. my specs are OSX 10.1.5, LimeWire Pro 2.6.5, JRE 1.3.1.
LimeWire pro support was not able to help me at all so I'm hoping one of the java Limewire programmers will help...

I get this message when I select a category such as video or audio and fill in some options and hit the search button. no search panel is every created and the app just write this output to out.txt.

thanks in advance.
