Sorted it! It was directing to the User directory where Java 7 was installed and not the System directory where Java 6 is installed. To solve it to go Your HDD/System/Library/Java/JavaVirtualMachines and Make sure '1.6.0.jdk' is there. Then navigate to Your HDD/Library/Java/JavaVirtualMachines and delete the Java 7 folder.
