Hey Redigit
! my friend has this problem with terraria. He changed his hard disk and his terraria doesnt launch anymore. A 800x600 terraria window pops up not responding. then after like 2 secs it closes. We've tried everything, reinstalling the game, using compatibility mode. Nothing worked.
If you can't find a solution there, make a thread with the details of your issue. It's much more efficient than spamming profiles of the devs.
