mema.....don't worry about your age...I will be 41 this year and was still able to get in to an AD!!!
I guess, try to re-word your on line application to the points of experience that they are looking for, you will find those in the company profile and mission statement...
Re-write your CV accordingly, add some bullet points of how your experience matches their requirements etc..
I am still not in myself either and this wait is killing me, but regardless of outcome, I have done better the second time around and will feel more comfortable next time if no luck this year either (fingers crossed to the opposite).
Best of luck to you and chin up...it is all about the way you word your cover letter and CV and answer the on line application questions....know what the role REALLY is and match your credentials to it.
