Can't seem to get the most basic SOAP interface to work

No matter what I do, I get this error response: (101) Invalid ListID

I have tried just about every workaround I can think of: php soap extension, nusoap, curl, etc. and then I even ran across this little gem: … criber.Add.  I add my API Key, ListID (which I have verified is valid multiple times), an email address and name, hit "Invoke" and I get:

<?xml version="1.0" encoding="utf-8"?>
<Result xmlns:xsi="" xmlns:xsd="" xmlns="">
  <Message>Invalid ListID</Message>

What's the deal?

Are you sure you're using a valid API key and list ID?

- API key is available via the Account Settings page where it says "Your API Key: ..."
- List ID is available from the Edit List page (accessible by clicking the "edit list name/type" link from the list details page)

If you're sure you're providing the correct details, then you're probably best to contact support with the specifics.
