Hi, Thanks you for you answers, however it doesn't make any sense. What you are telling me, is that those entry. Are somehow extracted from there respective BSA, before they are even enabled ? WHY? I have read the wiki, i have watch Both gother and "official step video" as well as others guide and resources about mod organizer. As a last effort I did reinstall windows, reinstall steam(obviouly), reinstalled skyrim. reinstalled mod organizer . and launched skyrim throught mod organizer and I do get a CTD. I launch Skyrim thought steam without those ghost entry as a pristine data folder = no issues. I launch Skyrim with or without DLC, thought mod organizer + those ghost enrty (original ini, without any mod "pure vanilla". I get CTD as soon as I load a new game). Now the only constants here is those ghost entry that should not be there. why would they be out of there BSA ? (specifically why mod organizer extract them to what purpose?) The other constant is the BSA. as I didn't re download them, but instead used them from the vanilla backup = done as per step installation. Now I'm not saying you are wrong, I'm only saying I do not understand. Please refer me to the require piece on the wiki or the exact video, because I don't remember having seen those issues addressed. And the most intriguing thing is that if I do not touch anything in mod organizer, the first time I install it, those ghost entry are not present. The game launch correctly. But as soon I as I try to touch load order (First install = load order isn't correct) those entry pops, and I get CTD.
