so basically most mods that I install with NMM are working but recently I ran on ECE mod and I really want it, but the problem is installing it, I tried everything, My SKSE is updated I even tried to manually install and then I tried to activate it through NMM but nothing works! what am I doing wrong? when I right click to active the mod it just loads for some seconds and then nothing, no error sign, and no activated sign. am I doing something wrong? can someone explain to me how to install it? did I miss something and I need to install another mod to install ECE? when I put my mouth over the skyrim sign it says legendary edition. (after it finishes to load it shows no sign of activate or error)
