I have this problem since 1.4 out. Before the game run normaly but now I can't play.
I do not think this problem is because I have an old PC , but idk. In a few days i can play with my "main" Pc... but in my second pc it dont work now .

Not 100% sure what's going on here, but have you tried reinstalling XNA? You can go to your Terraria Steam installation folder and run xnafx40_redist to try reinstalling it. Let me know if that helps!
