I've got a mod that's stuck on my NMM list. It isn't activated because as soon as I click on it it locks-up NMM! I've looked and other people have had the same problem with the mod. Is there any way to manually unistall a mod off NMM's list without clicking on it?

Open NMM's mod's folder (Usually something like C:/Games/Skyrim, but it may be somewhere else so look at NMM's settings as it should be stated there) and manually delete every reference to that mod.
