I put that warning against using the Steam Workshop version of TSLRCM for a reason. I suggest you read this on why using Steam Workshop is NOT recommended:
This is why I do not use the Steam Workshop, and I will not provide support for Steam Workshop. If you encounter bugs because you are using the Steam Workshop, tweaking a few files does not guarantee you won't encounter any more bugs, so I suggest you just reinstall KotOR 2, use the installer version of TSLRCM instead and reinstall my mod and other mods you want to use. Installing manually may sound like a hassle but that is the best way to avoid bugs and conflicts.
