MP seems to be broken

[madmatg]

hey guys, im loving single player and i hate to be complaining so much aready but...
multiplayer seems impossible ATM, i have tried with 2 different people to play since it came out. have reinstalled 3x and each time RTW says incompatible game data, it recognizes both of us as having the exact same mod(same numbers and stuff) but still shows up incompatible . i dont know exactly what you guys might be able to do about this but if you got any ideas i'd love to have them

EDIT:
more info
tried it with 3 people now and smae result however we are getting different version numbers for the new guy segfaulter
mine and icemans are 757BD26E:0
his is 36AESC80:0
again none of them work even though iceman and i had the same number
