It is much easier to play with a friend and do like was posted before in another thread with shaking the coffins and such than trying to play with 2 players of your own. Yes it can be done, but unless you know how to do it properly you are wasting your time. Beside if everyone now starts trying to play a game with themselves and a mule, you will never get a game up to play.
) Log 1 Person in at a time, if you don't you will get an error when trying to do both at the same time. (for those who don't know) 

dont worry your not alone I do that too!! Its more entertaining!!! Well my brother thinks so anyways, he stands there watching me jump from computer to computer laughing his head off, you'd think he'd help once in a while!!
