i downloaded the version where it installs itself. and whenever i try to launch the installer it say's 'Please be sure you have terraria in you steamapps folder, and it's a legitimate copy'. I downloaded terraria via steam and installed it too so it's legitimate and should be in steamapps. i don't get why i get this error.
