I also have had this issue. I purchased several texture packs and skins. I was playing with them fine this morning (several hours). I logged out to feed my baby and when I logged back in, all my purchases were gone from my account... yes I tried looking in the Marketplace and they are removed from there too... Is there a fix for this? This is really getting me to where I dont want to play Minecraft anymore.
