Grand Campeign - Hotseat?

Hi everyone,
I had MTWII 1.2 on HD when I installed Kingdoms Expansion. Now, when I try to start the Grand Campeign via the autostartmenu of Kingdoms the original CD is demanded. If I use the DVD of the main game everything works, but it is the balance of 1.2 and in the MP-menu doesn't give me the option of hotseat - so: How can I start a Grand Campeign Hotseat-Game?

on the same forum you will find many ongoing hotseat games, some might need players.

Grand campaing is hard to play with hotseat -try crusades campaing. In my opinion this is best for hot seat.
