I currently have Borland JBuilder 5 Personall installed on the machine I want to run LimeWire and it comes with the JDE 1.3.0. Do I absolutely need to download the 1.3.1 for LimeWire to run properly?

On another note, I easily installed it on an another system running JBuilder 6 (with JDE 1.3.1). Perhaps I should just upgrade.

Thanks
