I have the latest version, but everytime I try to add a Kotor 2 mod it says that the mod is for Kotor 1. These are obvious mods such as the Droid Planet.
Somebody may have either created the KMM file incorrectly or you have it set to install to K1 instead of K2 by accident. If it is the first the simplest way of correcting the problem is to delete the KMM file with the mod and then restart KMM. After that just treat the mod as if it never had a KMM file and add it to your list and place the files in there proper folders. It will then create a new KMM file for the mod.
