Hello, I had that same error when I reinstalled everything too. Question: do you have M2TW Kingdoms, and have you installed it and then installed EB2 over that? I did that and it worked.

The EB2.1b release did not state that Kingdoms was required, but it actually is. (Omission on the part of the post writer?) If you are reinstalling everything, then you need to reinstall Kingdoms too. It says so in the general FAQ of EB2: EB2 is made exclusively to work on M2TW Kingdoms. I was so excited that when I installed M2TW I went on the EB2.1 trying to get at the game fast, but completely forgot Kingdoms. Once I realised this and reinstalled everything again, it worked perfectly.

Hope this helps.


I have M2TW Gold Edition, but when I understand you right, than I have to install the addons too (American, Britain, etc.)? I´ll try this. And yes, I have first installed the maingame, then start a campaign, quit it, and installed then EBII (also when I reinstalled all). I thought "Kingdoms" is the maingame and the other addons are "britain, crusade, american". I´ll try this and will answer.
