Prophecies Campaign

I tried searching this but no results.
So my question is...
I beat the last mission of that campaign and it says or I think its telling me, I'm still on it. I forget the last mission, I believe its ring of fire, is this telling me I have to do this mission over to advance to my next step to completing this campaign?

Right now, the only released version of the game is the original version, the version with the prophecies campaign. Once Factions is released, you will be able to travel to Cantha and switch to the new campaign.
It is just part of the update in preperation for Factions.

The last mission is Hells Precipice. If you've beaten it go kneel in front of Glint in Droknar's Forge to get the Titan Quests started. Also visit Deldrimor War Camp/Sorrows Furnace and Temple of Ages/UW/FoW if you havent' already for more quests.
