I have approved an advertiser but ads dont show up

I had a request from an advertiser yesterday and i approved that ad.
i have adcode running on my site but still after 12 hrs, i see only fallback ads

also in my advertiser list : http://advertising.digitalpoint.com/...do=advertisers
it says : You don't currently have any advertisers.

but in http://advertising.digitalpoint.com/...eview&show=all
i can see approved ad
