When i start a game in single player the windows box appears for a second and dissappears again. Nothing happens.

This is the infolog

The last words are dutch and mean: invalid argument

looks like a network problem.
That means, it is most likely that spring tries to use a port that is already in use. Could be an other instance of spring still running, or an other software using the same port. default port is 8452.
