Major drop in InterClick CPM

I signed up for InterClick in early April and I was amazed to see I was getting an average of $1.30 CPM for in page banners on my arcade. So I added my other arcade and it only got $0.03 CPM. Then mid April the fist site I signed up with dropped from $1.30 CPM to $0.005-$0.05 CPM. I thought it was a low fill rate or something so I added default ads but my defaults were never used.
Has this happened to anyone else?
