OK, this is completely on the AdWords side. Certainly looks like something might have triggered a human review which can take a few days. Really surprised that it has taken a week though. Moving your mouse over the little message bubble in front of "Under Review" may give you some insight. If if doesn't, I would go ahead and call AdWords support. Have your customer ID ready when you do. You can find the support number by country here: http://support.google.com/adwords/bin/answer.py?hl=en&answer=1385067
