Hello, As I had many problems playing with my brothers together at the same time on the internet, I recently bought a new copy of Emperor. In my registry, I can find a key named "serial" (@ HKEY_LOCAL_MACHINESOFTWAREWestwoodEmperor). The problem is if i change the value of this key to the new serial digits (without the "-"), the game just doesn't work because the serial doesn't seem to be valid to Emperor (idd, the numbers aren't in the right order). How can I change my serial without reinstalling the game ?
