Powershell can't find modules that worked before

Question

Hi All, I am hoping someone can provide a simple solution to my question. For starters, here is what I am working with:
OS: Windows Server 2012 R2 setup in an RDS farm configuration
Powershell Info:
Name                           Value                                                                                  
PSVersion                      4.0                                                                                    
WSManStackVersion              3.0                                                                                    
SerializationVersion           1.1.0.1                                                                                
CLRVersion                     4.0.30319.34209                                                                        
BuildVersion                   6.3.9600.17400                                                                         
PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0}                                                                   
PSRemotingProtocolVersion      2.2       
About a week ago I was able to launch powershell, type import-module remotedesktop and press enter so that I could perform various RDS functions in Powershell that cannot be done through the Windows GUI.
Now when I attempt to do so, I get the following:
import-module : Could not load file or assembly 'Microsoft.RemoteDesktopServices.Management.Activities,
Version=6.3.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find
the file specified.
At line:1 char:1
+ import-module remotedesktop
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [Import-Module], FileNotFoundException
    + FullyQualifiedErrorId : FormatXmlUpdateException,Microsoft.PowerShell.Commands.ImportModuleCommand
When I look under C:\Windows\System32\WindowsPowerShell\v1.0\Modules I can see a folder for RemoteDesktop and it contains Powershell scriptmodules. No windows updates were applied to the server and the event logs are clean as a whistle.
My question is simple, what did I do wrong?
Update:
when I open a command prompt window and type
"powershell -importsystemmodules", I am then able to proceed to
import-module remotedesktop from the CMD prompt and perform the functions that I need to do. Not sure why in the world this would suddenly work only under CMD and not Powershell.
