Hi, this is my first post here (it's a fantastic site and community). I searched the forums, google, etc for answers to this but have come up with nothing that works. My problem is pretty common: I have about 15 mods installed, one of which is the Climates of Tamriel package. When I play the game they all work except for COT. If I look at the Data Files tab in the launcher, the COT esm is always unchecked (the corresponding esp files are checked). If I check it, close the window, then open it right away it's unchecked again. It just won't stick. I have run the game through NMM and without it: same results. My plugins.txt is not read-only, nor is my skyrimprefs.txt. I don't have any mods installed which should conflict with COT. I've used BOSS and it says everything is perfect, checks out fine. When I originally installed the COT mod it even worked (this is my second install). Any and all help is greatly appreciated.
