I have tried to tun this from Steam and have received an activation limit reached message from securom.
I have emailed securom who will not do anything and say you need to contact either steam or the publisher, Steam will not deal with external activations and Warner brothers tell you to contact either securom or steam.
People wonder why Pc games are pirated. This is a game registered to my steam account with over 8 hours play time and many achievements unlocked. It seems once you hit the securom activation limit the only way to play the game is to re-buy it or use other methods.
Useless.....
