Need unupgraded, recruited dragons. Purchased ones won't work. Try clicking on the portal several times. In version 3.0, this helped me. Two patch options: 1. 1.6 cumulative + bug fix: http://forums.ag.ru/?board=heroes5&action=display&s=0&num=1192719850&start=125 (post 146) 2. 1.4 + 1.5. Official patches don't install properly on a disc made by incompetent pirates. If you decide to buy a license, I recommend buying Tribes of the East. It doesn't require the original game for installation. There is a mod that allows you to play all the campaigns of the original game and Tribes of the East in versions 3.0 and 3.1.
