Windows PowerShell ISE - New-NAVCRMTable

Hi people, i would like to execute this script by PowerShell:

New-NAVCRMTable –CRMServerMyOrg.Crm4.Dynamics.Com –EntityLogicalName systemuser,campaign –ObjectId 5340,50001 –Name “CRM Systemuser”,“CRM Campaign” –OutputPath c:\CRMObjects

but it can not find cmlet New-NAVCRMTable. Any suggestion? I imagine i have to import a module with Import-Module but i dont know where it is.

Thanks in advance.
