Minecraft addon will not update in marketplace

Purchased and downloaded "My Life in Sakura Shores" pack.  It ran fine for several weeks.  Tried to create a new world and it said there was an update.  Clicked on update button and nothing happened.  Tried several times.  Removed and reinstalled pack.  Again it indicated an update was available.  Tried to download update and nothing happens.  Cannot create new worlds with pack.
