Yep they modified the grouping in both the left leg and arm thats why your old morphs dont work and you need the upgrade. as far as downloading from your account page or the patches on the product pages. you can do it from the product pages but if you want to archive the whole model with the fixes intact. I would redownload the full files. which have been updated.(of course if you are on dialup, that could be a lot of downloading)
