I decided to delete the game entirely thinking that there must be a bug or something. Then I went in to my ArenaNet account to download it and now this stupid computer won't let me download the game! and here I thought going to a Mac would be better for me. I just had put the High Sierra OS in so I don't know if that is stopping it or not. Have had a ticket in for a week now and have jumped through every hoop they told me too, but no luck yet. Anyone have any ideas, because I am fresh out and just going crazy trying to make this do what I want it to.
