Problem with Titan quest, cd key invalid (thq bundle)

from what i know, the company behind the game went out of business and there is a fan patch but you will need to get immortal throne for it to work.

I have the same problem, no idea how you could fix it.

They were having invalid CD Key problems two years ago.

Same problem here upon checking, which is really REALLY awful, since this game rules in multiplayer.

there's a new support article on the Humble Bundle site that might be related to this

I had to trade for my copy, so I'm hoping this gets resolved or else I will have to hope the person I bought it from can send a support ticket for me.

Bump, anybody find solution for this? Running steam as admin didnt work for me... I hears about that THQ know about this problem and solving it with steam, can anybody confirm this?
