Hi XP5 - the only way I can think how something like that would happen is if your installation was corrupted somehow. Make sure you're not running any kind of altered version of MoI like a crack for example.

If you can send me an e-mail with your license key in it, I can send you a new download link to the installer so you can be sure that you have a proper non-corrupted installer to start out with for re-installation.
