AddUser2 not working as expected, or I'm doing something wrong.

All,

I am trying to add a new user to EPDM using the API call AddUser2. The source code I'm using is directly from the 2012 API_GB.chm help guide and is repeated below. When I try to run the code I get an "Access is Denied" error at the userMgr.AddUser2 call in the CreateUser sub. I have created several test vaults and configured them to use different Login methods (and to make sure I hadn't enabled/disabled some permission in existing vaults) but nothing I do seams to alleviate this problem. Does anyone have any suggestions or sample code that works for them? Other pertinent information: I’m using Visual Studio 2010, building a .Net 4.0 assembly, and referencing PDMWorks Enterprise 2012 Type library (COM) version 5.15. Thanks for your help.
