This is the error I receive, I have put the Nterraria files into the Terraria files through steamapps>common>Terraria ect. So I have no clue what is wrong with it. Id like some help because its also happening to my other friend. Hope you can help me with this error, As I have played it before at a previous version and would like to play it again since its a modded version of Terraria 1.3.0.8
