I am attempting to create a task on my sharepoint task list from the "Task" Tab in the Infopath Event Wizard.  When my process executes this activity gets an error and my process stops.  The error message is shown below.  I believe it is an access issue, but I can't seem to get around it.  Any help would be greatly appreciated.

System.Net.WebException: The request failed with HTTP status 401: Unauthorized.
