Problem running a VMware vCenter Converter Standalone 6.0 SDK locally for a Convert operation.

Short description of the situation:

We are trying to run the VMware SDK for a convert operation on a local machine. We have installed the VMware vCenter Converter Standalone Client, the one with a GUI that you can manually convert with, but we would like to be able to do this with the SDK. The manual convert operations within the GUI all seem to be working fine, but whenever we attempt to do this within the SDK we keep getting errors that we have not been able to resolve internally.

Here is the basic information about the environment we have set up and the error:

Downloaded SDK:

* VMware-converter-sdk-6.0.0-2716716.zip

Error Info:
* "Failed login due to a bad user name or password"
* <InvalidLoginFault xmlns="urn:converter" xsi:type="vim25:InvalidLogin" xmlns:vim25="urn:vim25" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"></InvalidLoginFault>
* ConverterConnection.cs line 262

Environment:
* Windows XP SP3
* Firewall Disabled
* ___VMWare_Conv_SA___ user has been added to the administrator group.

Relevant SDK Properties:
operation.count=1
operation#0=Convert
source.type=Physical
source.physical.address=127.0.0.1
; Have tried machine name, local ip, and localhost as well
source.physical.username=administrator
; Have tried under the administrator account, under other accounts, using other admin privaleged users, all to no avail.
source.physical.password=adminpw
source.physical.ostype=windowsOs
source.physical.agentport=
source.physical.thumbprint=
source.physical.reboot=false

converter-server.xml changes:
<enableRemoteAccess>true</enableRemoteAccess>
<enableNonRootAccess>true</enableNonRootAccess>
<validatorEnabled>false</validatorEnabled>

We can provide more information about the client, server and agent setup if needed, although these were relatively unchanged. We also have attempted running the sdk on both http and http (http://localhost/converter/sdk, etc.).

Any help would be much appreciated ~
