Paid for texture packs locked again

 

Good evening

 

After playing the game for an hour today. I logged off to watch TV with the family. I have since logged back in a couple of hours later and my texture pack puredbcraft is now locked and asking to be paid for again.

 

How is this possible when I was using it earlier. I have closed the game and restarted but no avail. My avatar pack has also been returned to the default and I have lost my paid for avatar aswell

However my natural texture pack which I purchased on xbox360 version a long time ago is still usable.
