The items I no longer have are the following; Deep Sea mashup, Fallout mashup, anime academy, pureBDcraft, BlockPixel, Gamer skin pack, and The lord of fire and ice map.

I was using most of those items this afternoon and by the time I logged back in it sed I needed them to be unlocked even though I already bought them. There are a few other skin packs I bought that I can't recall what they where.
