Play Generals w/Crack on WW online?

[DacFr3akZ]

I tried all the stuff, read all the topics, but still I have this:

* Updated to version 1.2
* I can play without CD
* When I start MULTIPLAYER -> ONLINE, i'm getting the:
"Serial number is invalid. Please try another one"...

I have tried to change the serial number in the registry, but no luck.

The strange thing is, I have also tried the serial number my brother uses, and he bought the game. (note: we don't go online at the same time!)

Anybody any ideas?
