Problem with kingdoms!!!

[Monsieur Alphonse]

you can't play the grand campaign with Kingdoms (unless you use the retrofit mod). You have to insert the M2 disk to be able to play the grand campaign.

The Kingdoms expansion doesn't affect the original game in any way.

Unless you play with the retrofit mod (highly recommended) and then you play your grand campaign using the kingdoms disc.
