Problem: you are geting the following error when starting GooTool: "Uncaught exception (java.lang.RuntimeException) Can't start primary instance server"

Cause: It appears that a recent update to Vista added a "::1 localhost" line to the hosts file, causing Java to attempt to use IPv6 instead of IPv4 when resolving "localhost".

Solution: Upgrade GooTool to 0.10.3
