Problem with Callgirl/Escort service

Please help?  Never posted on here before so I am sorry if this has been answered before or if I've posted to the wrong place. 

I am having trouble with the call girl/escort service. My sim has reached High Class Escort status.The call girl service works as it should. But when she gets an Escort call. Everything works fine up until she asks for payment (they meet up, go to eat, dance, then go to woohoo). They enter the building she goes to ask for payment but the interaction gets cancelled and he leaves, ending the mission. I have tried uninstalling KW and reinstalling, tried making a complete new game (even reinstalling the whole game and re adding Mods). If the problem could be KW settings related, it would help to know what settings i should have. However, any help would be appreciated
