The statement "we have lives" means that because we have released a mod on here for free for your use it doesn't mean that we are at your beck and call if anything goes wrong, we give support as and when we can, i personally support all my mods all the time but i understand lifes pressures...etc that can cause some coders not to.
As it's free there aren't any warranties...etc so, paying for it is how you get those assurities
