You were right to start a new game (v0.4.4 was too old to transfer your saves). After summoning Soren and building the shop, don't forget to do the adventure board mission to unlock Zel's hero challenge ;)
I have nothing after building the shop, building the portal, recruiting Soren. There's nothing on the ongoing and neither in the new page of the adventure board. :/ Also, I reinstalled the game, so the old save files wouldn't affect the game, sadly this problem remains. :/
