Mods not working ion Skyrim (Workshop)

Hey guys, i did a complete system restore on my system and I installed my games. Well, I got skyrim installed and I got all my workshop mods and they all downloaded fine in steam and in the skyrim launcher. But when I play skyrim, some of these mods don't work. For exapmle, my Dovakin Muntain Retreat Mod works but my lightweight potions doesn't work. So, some mods work and some don't. Thanks for the help.
