Hm, the only way to find that out, is looking at the quest and conversation log, Shadow. If you have the Dragonarmour quest in your quest log - and went to P. - maybe you used that "killer sentence"? It appears right from the start - even before you lied.

Edit: About
Radeon - not all Radeon gamers had probs. Now, I'm not the tech expert, I can only read posts - but IIRC it was a main issue combo Radeon+DirectX 9 after the last patch. So far my memory doesn't betray me, the game came out with DirectX 6 compatibility originally. Though I DID wonder why the English gamers had more probs with Radeon than I could read/extract in the German section, even on the old forum. And Barnabus, the German tech crack, plays with Radeon himself = no probs.
[color:"yellow"]Lar/Larian Studios and Radeon? click here, please[/color]As Lar himself said that Beyond Divinity will be for DirectX 9, I hope, your Radeon prob then will not occur.
Another hope: As Beyond Divinity is planned to be more linear than Div, maybe questbreakers won't be so easy anymore either. I think the complexity (what I liked very much BTW) was a cause for busting some quests.
