I have been getting this message when trying to download mods through the nexus mod manager, ever since i updated my OS from windows 8.1 32 to windows 8.1 64. I had to re-download my games from steam already but the mod manager will not install some of the mods i want to re-download and even ones i haven't downloaded previously. I tried to go to the nexus mod folder in my program and create a file named "cache" but that didn't work, any thoughts on how to fix it? The message says There was an error registering this mod:[mod name]
