hi! i'm sorry it's not working for you :( here are some steps you can take -
1. Put the mod in OVERRIDES
This might resolve the issue completely!
2. Enable Debug Notifications to see if the mod is being loaded
Open the package with S3PE and then open the file called "Sims3.omedapixel.Decorating.Main" with Notepad.
Edit the line as shown in the picture to be "True"
Save and close everything and load up the game. When you switch in to Build/Buy mode, you sould get this message -
That means the mod is working!! If you DON'T get this message, then there must be a bigger problem and I'll need more information to help you troublshoot.
3. Set Keyboard Language to English (US)
For my PC (Windows 10) it's done like this - Click on the bottom taskbar near the time and date, where it likely says ENG or whatever language your keyboard is currently in.
Select ENG US if it's there. Otherwise click 'Language Preferences' and in the next screen, add ENG US as a new language.
You can switch your keyboard language temporarily while you're playing the game.
If this still doesn't help, please message me directly off anon! It'll be much easier to work out the problem that way :) This goes for anyone having issues with S3DT!
