So recently i completed every achievement in skyrim and did all the main quests, and i was quite bored, so i installed some mods from the official bethesda mods page on the skyrim main menu. these mods worked fine, but the collection of mods there was small. i saw a mod that looked good a while back before i completed the game, so i decided i'd try and install it now. im new to using vortex, and i watched a turorial on how to do it, but im still not sure whats happening. i installed the mod manually and then dragged it into vortex, opened skyrim, went to load order on bethesda mods page, and enabled it. the game crashed when it reloaded the files. i dont think this is what im meant to do, come to think of it, but when i played the game without going to the bethesda mods page it just wouldnt work at all. so i decided to install it directly from the page to vortex, game wouldnt even open. i tried enabling it while skyrim was open, still didnt work. i changed my mod locations are in a seperate folder from skyrim, like the video i watched suggested, but it still wouldnt open. ive tried everything. pleeeaaassseee help meee heres the link to mod site if you wanted https://www.nexusmods.com/skyrim/mods/48375?tab=description
