Because it works both for online and offline gameplay.

Because I had to include a secondary program (and his dependecies) that I coded to switch between online and offline mode.

someone help me wit this patch. i join a game then after bout 2 mins, all buildings blow and therefore defeated.

wat are u guys all doing different?

thanks.

This is not a problem with the patch. This is a problem with either
1. The game itself
2. You installed this patch on an incorrect version of the game

It's usually something to do with the serial number - either you have an invalid one or you changed it without reinstalling the game.

incorrect cd-key.

this even happens on lan games when players have the same key.
pretty nasty thing :)

Ok, so you still need a valid online key?!?

Of course
This will come with your original cd.
