I get an error when this code runs:

Fatal error:

* A required field called username is missing or has an invalid value.

Unable to proceed with save while $errors array is not empty in class vB_DataManager_User in [path]/includes/class_dm.php on line 849

The code I'm using is:

			$userdata =& datamanager_init('User', $vbulletin, ERRTYPE_ARRAY);
			$userdata->set('usergroupid', $new_group);

			$userdata->save();

which is what I copied from your post. Any idea as to why it's throwing that error?
