Kootali Facebook Clone Modification

Hi, I've been developing my site so far using the kootali facebook clone script but have run into a few problems. For some reason the friends request system is very buggy and will only allow a user to connect with member "0", in other words no one. I've tried endlessly to get in contact with them but they keep ignoring my messages, so i've come here to get this sorted. Please only bid if you know the script (kootali facebook clone) and the how it generally works I can provide a copy of the original script without my development to whoever I give this project to, seems only fair as they took my money and left me with a half finished product. Thanks Thanks
