@3_rolyat_3 Okay, why don't we start over, just to eliminate a bunch of potential issues at once. First of all, what is the patch level of your game? You can see it in the lower left corner of the launcher. Both 1.67 and 1.69 are current, but any earlier and we'd know why the mods weren't working.
So: Pull your entire TS3 game folder out of Documents and onto your desktop. Then launch the game up to the Main Menu (no need to load a town), which will spawn a clean folder with no content, including no mods. (Your saves will be in your old folder, but leave them there for now.) Then go into your new game folder and delete the five cache files listed above. Create your Mods folder, and inside of it place the resource.cfg file and make a Packages folder. (Note: The resource file does not go into the Packages folder, it sits in the Mods folder next to Packages.) And make sure that the M in Mods and the P in Packages are capitalized.
Next, go to NRaas and download the MasterController base mod only, but make sure it's the one that works with patch levels 1.66-1.69. (It's the first download listed.) Unzip the file and place it in Mods\Packages. Launch your game again. When you get to the Main Menu, you should see a popup telling you that the game has detected MasterController.
Once you've done this, let me know whether the mod shows up at the Main Menu.
