Orchestrator Powershell Plugin errors

I am trying to get the Powershell plugin to work in VM Orchestrator. I am pretty new to this and this is completely a test lab situation. I have the Plug successfully installed and the Powershell host has been successfully added. The powershell script that I am trying to run is a simple script that just renames a VM. The script runs fine from powershell but when I run it from the VCO, I get the follwoing:

[2014-04-18 13:21:00.992] [D] Invoke command in session aa481839-7cfe-42ce-8a73-71e6344128c6

[2014-04-18 13:21:22.918] [I] PowerShellInvocationError: Errors found while executing script

of type 'System.OutOfMemoryException' was thrown.

   tion,VMware.VimAutomation.ViCore.Cmdlets.Commands.ConnectVIServer

The script is as follows:

param ($OldName,$NewName)

add-pssnapin Vmware.VimAutomation.Core

$username='vc55-1\VMSrvAct'

$password='******'

Connect-VIServer'VC55-1'-username$username-password$password-force

$CurrentName=get-vm$OldName

set-vm-vm$CurrentName-Name$NewName-Confirm:$false

Disconnect-VIServer'vc55-1'-confirm:$false

The Environment consists of 3 servers.

1) A VM 5.5 Host

2) A W2008R2 5.5 Virtual Center

3) A w@008R2w@008R2 5.5 Orchestrator server with Powershell Plugin  1.0.3

It looks like it is failing onf the Connect-VIServer but this works when I run it by itself. Any help would be greatly appreciated.
