Help with the achievement of a chatterbox!!

[Noodles]

I go up and talk to Whitman first time all is well,but the second time I can not talk to him.why?

[Yobilat]

Had same error. Had 30 scrap when I talked to him first time and he wouldn't talk to me second time. I've started a new game and talked to him first time while having 0 scrap (collected all 50 scrap after i talked to him) and it worked. I don't know if is there any fix that doesn't invovle starting a new game but that worked for me.

I started from the beginning 3 times!!You talked to him,collecting details and more time talking?

I could go look it up..but what are we talking about here? How exactly are we supposed to unlock the chatterbox achievment?

I've read that the second conversation isn't required to get the achievement.
Started a new game yesterday and had the same problem.

I went through the game but I was not given the achievement.

I can confirm that I got the achievement without having the second conversation with Dr. Whitman.
Maybe you missed someone. Here's the guide that I used : http://www.youtube.com/watch?v=z9flCTdLqO8
