adcenter estimation showing 0 traffic

I just created a new adcenter account and started a campaign with like 50 keywords.

The traffic estimator shows 0 traffic.

I was wondering how come?

Do you think it takes a while for information to be setup?

Is it because the campaign and account are both new?

PS: I have added a payment method

Or maybe my bids are too low? (I set them at $3.00 to experiment but it still says 0)

Any advice?

It takes several hours before your ad go's live!!!

Thanks for the tip boss - I noticed that my "quality score" shows a "-"

Is that bad?

Or does it just take time?

THANKS FOR YOUR SUPPORT
