Something went wrong with FrostWire.
Maybe you're using the wrong version of Java?
(FrostWire is tested against and works best with with Sun's JRE, Java 1.4+)
The version of Java in your PATH is:
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0-b105, mixed mode)
