I found a few errors the same as many of the previous posters here... I quickly tried the older version found here and it works fine!

You don't have any snazzy admincp areas to help you keep it all organized but it works better IMO. If anyone needs help w/ the older version or ?'s on how to add more "blocks" then simply PM me for assistance - this is not one of my mod threads so I most likely will not be checking back here again unless I browse etc so please PM for help instead of posting, if it works then we post here what we did!
S-MAN
Edit: Ohh and I will be testing this for a 3.7.4 board this weekend (the older, stable version like I mentioned above) so I will post if it works after the test!
