Did you begin by doing a clarifying cleanse? If not, the silicone buildup from before may have kept you from seeing results.

Another possibility is that you may have had hidden silicones in the products you were using when you thought you were CG. You sure wouldn't be the first person to have that problem.

Also, some people have problems with polyquaterium buildup. They're supposed to be water soluble, but some combinations of products contain so much of them that it can be a problem.
