I think it's 1,000 impressions before they start to 'mark' keywords as disabled. But I'm not entirely sure.
With only 431 impressions, at the standard CTR (click through rate) of half-1%, you would only have gotten 2-4 click-through's anyway. So zero isnt that far off. Basically you just havent tested this one long enough to know whether it will pan out or not.
Here's what I would do: Duplicate that campaign by coming up with new keyword lists around other related phrases (related to your ad). Create ads that contain this word/phrase that is consistent throughout your list. Set up a new campaign for each of these, and continue to do so and monitor each one. You are bound to find keywords that bring you traffic and that convert for you.
