Argh no elven campaign yet
 

Darn, i screwed it. I write this for others, so that they avoid my mistake.

I started a campaign under ID "HeroMan" and played human campaign.

After a while i also started the Orc Campaign under "HeroOrc", because i was curios, how the orcs are played.

I finished human campaign.

I pushed orc campaign to unlock the elven campaign soon.

Orc campaign finished, but no elven campaign.

Then i understood, that u have to finish the human campaign and then the orc campaign under the same player-ID to unlock the elven campaign. Makes sense, but i wasn't aware of it.

OK, this game is big fun anyways, so to play the orc campaign again isn't a pain - i can emphasize different units etc.
