Hey I have been wanting to play Gunz few days now, but i get this weird error. I can install game normally and it updates everything, also gameguard gets updated, but right after gameguards authentication i get error:

Protection Error
Error: 103

and

Memory cant be written

I dont know what to do. I have tried disabling my firewall but nothing.
im running windows XP sp2 and F-secure 2007

Thanks in advance
