Installing Superstar

[jack-o-blades]

Hey, i just signed up to this site hoping that someone would be able to tell me lets me know why after i install sims and install sims superstar that my sims allways hate each other.
Before superstar gets installed they are fine with each other the talk and get a Green + over their head but with it installed when they talk to anyone its a big red -. so i cant get them to go to sleep or share a bed and they end up dieing. Is there anyway to sort this out??

Thanks
