moved your post over here to the dedicated Adwords forum
If you look at this forum you'll see you're not alone. The reporting functions are down or not working properly for many people from different countries.
I'm starting to wonder if this is just the inability on Google's side to get it fixed or if there's something in the works with adwords.
After all the delays in reporting have been on and off for several weeks now.
If your ads are not appearing then it's probable that your click through rate (CTR) has dropped below .05% or, in other words, less than 5 clickthroughs for every 1000 impressions. If this is the case then there should be a red asterik beside the term and an explanation below.
The other thing it could be is a problem with your credit card or an editorial problem.
