Normally when you click the .bat, the mod selector comes up, you choose your hacks and click build. When it's done the cmd prompt will say press any key to continue and you'll have a second .swf called client-mod which is your hacked client.
If that doesn't happen, try uninstalling your java and make sure you have the latest one and check to see if there are any spaces in the path to the mod selector.
If nothing works then there's always the hacked clients in the hacked clients folder you can use.
