I seem to be having an issue with the sims blender plugin. I've been using it with Blender 2.76b I think and the plugin seems to have randomly broke. I keep receiving this message anytime I try to load props or cas. I tried removing the plugin and redownloading it. I tired downgrading blender to the version the plugin was made for and I still receive this message. Does anyone else have this problem, or does anyone know how to fix it

bump, im still getting this error
