Hi Immanuel!
I read on another post that the problem is NO-CD + Service Pack 2... :P
I use Windows XP and itīs always updated.
With all NO-CDs that I have found to version 1.1 until now, the game begins and I can play for several minutes. Then the game freezes and I have to reboot the computer.
Anyway there are differences between US and UK as there are two different patches.
