I have been a fan for quite some time now. Unfortunately I have been away and unable to play for a few months. Let's say I was detained for 4½ month. Anyway, I had finished previous content and really want to see what's happened since I was away but cannot figure out how to update the game without having to pay for it again and redownload. It was free when I first downloaded it then i actually paid last time because I had to redownload so how do I get the new version without paying for it again?
