Sur un forum y a marqué ça:
make sure KB917422 isn´t installed first
Start > Control Panel > Add Remove Programs > check the show updates box
scroll all the way down, if you see KB917422 uninstall it.
next leave the game installed. reinstall EAD. try game again.
if that doesnt work, Close EAD try loading the game
Sinon il parrait c´est un problème de sécurité (anti-privacy)
