Unable to create CRM Organisation using Powershell

Hi,

I am trying to create a CRM Organisation on-premise using powershell, but I encounter the following error

New-CrmOrganization : Source    : mscorlib

I am using the following command to create the Organisation:

Add-PSSnapin Microsoft.Crm.PowerShell
New-CrmOrganization -DisplayName "TestOrg" -SQLServerName "SR12R2" -SrsUrl "http://sr12r2/ReportServer" -Name "TestOrg" -BaseCurrencyCode "USD" -BaseCurrencyName "US Dollar" -BaseCurrencySymbol "$" -BaseCurrencyPrecision "2" -BaseLanguageCode 1033 -SqlCollation "Latin1_General_CI_AI" -SQMOptIn false

I already have deployment administrator rights, and I can create Organisations using the Deployment Manager, but it doesn't work via powershell. Also, I have tried running the powershell "as administrator" but had no luck.
