SimPE Name Changing

Hello. Does anyone here have experience w SimPE?

I’ve started a new neighborhood and for the first time from scratch am making all downtownies and townies myself. No Maxis ones.

But as I go into PE to change the townies names after I’ve made them and sent them out into the world, it says that all names in the hood are unknown!!

I tried doing it before I made them townies too to no avail.

This is the method I’ve used:

Loaded neighborhood
Tools > Neighborhood > Neighborhood Browserr

Neighborhood > Sim Browser

Also tried going to Sim Description.
