Hi, guys! I am trying to use S4PE to add more names to the townies in my game according to https://www.youtube.com/watch?v=Ou-BgtOsvnA, but I keep getting these errors once I try to create the package.

Once I add the DATA file:

Error reading resource 0x545AC67A-0x006CA304-0x7036FF3703847744

Once I add the XML file:

Some resource names may not be displayed.

Can someone help me to solve it? Or at least recommend me an application where I can put the two files together (I have Sims 4 Studio, but I don't know if I can do it there). Spent nearly a month adding new names, don't want all this time to go to waste...

That guide is nearly 10 years old and S4PE hasn't had a update in 4 years.

In S4S create a new package.

Tools > Create Empty Package

Once you name and save the package.

Tools > Game File Cruiser

Paste this in Instance field box 7036FF3703847744 then click all. Click add to current package.
Do the same for 784760DD00959DFA (click in say name field to make it load the next instance once pasted)
