I haven’t logged into the game for a long time and I was offered a Ladder Pack, but I couldn’t accept it. After the time expired (7 days), when I log into Hearthstone (Standard mode), a window pops up saying ‘Choose a Pack.’ I try to select a Paladin or Warlock pack (I’ve clicked all the buttons), but nothing happens. I can’t start a match or play the game at all.
I was playing on my phone. What should I do?
