Hopefully the functions are not unique to each person, that would be a huge **** move from Kerberos(not like they are a good dev company anyway). If they are all unique I would say drop the game and not worry about anything from Kerberos again because they seem to go out of thier way to make everything about the games they make difficult to deal with.
It's good to see that it works for you guys also. I still find it odd that 0x90 had the same version and everything but the game was doing stuff differently for him. Oh well, it's sorted out so it's all good.
