Power on and force recustomization

Hi,

Running vCO (the version bundled with vCenter 5.1) and vCloud 5.1 and trying to instansiate a vApp and then force recustomization using the package in this thread http://communities.vmware.com/thread/393562?start=0&tstart=0

I'm looping through all VMs in an app, in my test app there is only one, the machine powers on and the workflow finishes without errors, but in vCloud I get this error:

"Guest customization failed on this virtual machine. Error is : 'Required parameter missing. ReconfigToken not found'"

Anyone have any ideas on why?
