Tomisama are you sure about the CD thing? cos i jsut tried playing a campaign battle, and in the middle of it, i took the cd out and it resumed with no problem.. the cd just has the start-up? or wut ever ^^
its the same for other games, i remember when i used to attend lan aprties where 6 ppl would share one cd for battlefield 2, warcraft etc.

my problem is that i cant get my vista and xp probaly connected to each other via lan...
