Command and Conquer Generals problem.
 

When i played with a network pc with this game, After a few minutes all buildings explodes... why is this happening?

can someone help

This SOUNDS like an extra copy protection kicking in. I think one of the previous Westwood RTS'ses like Red Alert II had the same 'feature'. Try to play with the originals and without any crack and see if the same thing happens.

I install the game from cd and it works, but when i copied the file to other pc, using just copy, it will be likethat. just go boom :)

Is there a bug? or is there some files that westwood try to hide during installation?

When you buy the game NEXT WEEK, you will find out if EA Pacific are hiding any files. You dont know what I mean?

Nevermind...
