Hi, James! I brought my Mac to work the other day to ask one of my IT colleagues to look at the issue. And guess what? He fixed it.
It was something with the read privileges as you said, but other than that I don't it. Thanks for a lot for your support, though. :) Looking forward to getting started playing.
NO WAY! I'm so glad you got it fixed! Thanks for following up here, by the way: it's good to know what caused this so that if it happens again I can tell that person "um hey look it's almost definitely the read privileges".
Hope you like the game now you've finally got it working! :)
