Just forget this game. This is a broken game without any support. The game engine has major faults, dev team knows about it but they dont do anything. They promised fixpatch at march 2011. It never came up. I've leaved message in wasteland forum. No answers for a MOUNTH. The company is in bankrupt or it just doesn't work anymore.
Invest your money for games which are good and well supported. A good examples are Gary Grigsby War in the east, Panzer Corps etc.
