After installing the game I got for free some time ago I now get an error when I try to start the game. The error is in Dutch so the translation could be a bit off, but it says: license date could not be written, contact customer support for more details.
I didn't even enter the serial I got so I wonder what the problem is.
I did reinstall the game to another hard drive after I noticed my drive where I first installed it only had 60mb left over. It might have something to do with that.
