Black and White Backup --- No way to multiplayer?

[Ediaksirt]

Okay people is there anyone who can help me out?
Got me a backup of Black and White (German Version) and cracked it with the patch. I also own my own unique Serial...but if I play with the backup Multiplayer just ain't possible. I can Login - the game accepts my Login and Password but no games appear in the list. Someone mentioned you can only see people on the list who got the same .exe -file...
Dunno,anyone who can help me out?
luv yall,
