Well, i installed the game without problems and started it, no problems in menu but when i try to start a game, it keeps loading for some time and then freezes and i have to press ctrl+alt+del to close the game. and then i get the message
"ASSERT(fMaxWindSpeed > 0.0f) : line=294, file=D:\projectszW3D\main\Worms3D\WindMeterEntiry. ccp"
what can i do?

Tried reinstalling? Have the service pack from www.worms3.com

Ok, i´ll download the pacth and try it.
