 * Have you tried the latest version of Advertising Manager? You mentioned that 
   you were using 3.4.4. Can you try 3.4.8? If you are still having the same problem
   with 3.4.8, I can help you from there.
 * Sorry for the delay here – you caught me in the midst of traveling.
 * Scott

   activated because it triggered a fatal error.
