Have you experienced Error Code: 6 Type: 421? Any known solutions for this one - whitout having to re-install the game?

Thanks

i have the problem too :-( pls help !!

It was an error with the Gameguard update. Just try to start the patcher as normal and let gameguard update.
You could also go into C:/Windows/System32/drivers/etc/hosts.

Open hosts with notepad and delete everything at the bottom without "#"
