Can anyone help me? I play Empire at War often. I even got the Forces of Corruption expansion pack. I was looking on the Internet when I found single player cheat codes.

The codes are:
press ~, or (shift)+(tab) and then type
"CHEAT_Empire_Spawn_Fett" to Spawn Boba Fett
"CHEAT_Empire_Spawn_Veers" to Spawn Colonel Veers
"CHEAT_Empire_Spawn_Vader" to Spawn Darth Vader
"CHEAT_Empire_Spawn_Emperor " to Spawn The Emperor

I can't get these to work!
I have tried these and many variations
I have tried under both the original and expansion
I have checked many websites (they all say the same thing)

I don't know if this matters, but I tried with the expansion disc and the original disc. This made no difference.
