i did just post on there forums and said that we could play 1.5 since that most of them aldy installed it and lots of peeps are having problems running both versions on their comps..i told them that TWL has not mandated the 1.5 version but unless they hear otherwise then we will match with the 1.5 version..i played it last night and had noproblems but its up to yall what version yall want to play
