Problema al instalar LimeWire

Bueno, iba yo tan contento con mi limewire y me sale el siguiente error al instalar:

Código:

java.lang.StringIndexOutOfBoundsException: String index out of range: -4

Yo creo que es problema del J2RE, porque anteriormente tuve que instalarlo. Puede ser que el que tengo yo tenga un bug o sea una versión antigua, pero, en cualquier caso, a ver si me pueden asegurar algo.
