Thank you for the reply, Kostas. I have just received a similar request from Stanislav Grinberg at Google's API division, and have sent it along to him.

You can view the exact same things as I sent to him by checking any of the demo scripts in the API developers section. Literally the only things we changed were the login name, the login password, the user agent string and the token. We have tried both our AdWords login info (first) and our API login info using each of the technologies (except the Java) with the same (non-)result.

I'll re-post when I hear back from Mr. Grinberg ... probably (hopefully) next week.

Just for fun ... here's the demo XML file we're using (w/changed acct info):

Thanks again.
