hello everyone… i have problem with downloading the game i just dont know what to do. and i have the key code
Here you can activate your key. You can also download the Automation Launcher from there (which is the same as the Demo Launcher). If you need more info, just ask! 
I get errors on startup o know this is off topic but I need to tell someone, I get a weird LUA error due to file loss and one of the game files are corrupted PLEASE HELP!!! 
P.S. this was caused by a botched update patch
With a corrupted install, only a reinstall really helps :s
