Get-MpPreference fails: 'Defender' module couldn't be loaded.

Hi, everyone!
I am on a Windows 8.1 and I am trying to use the Windows Defender WMI providers via Powershell. I have last used this machine about 2 months ago and there were no troubles with it. Now when I run `Get-MpPreference` cmdlet it fails with the message:
Get-MpPreference : The 'Get-MpPreference' command was found in the module 'Defender', but the module could not be loaded. For more information, run 'Import-Module Defender'. At line:1 char:1 + Get-MpPreference + ~~~~~~~~~~~~~~~~ + CategoryInfo : ObjectNotFound: (Get-MpPreference:String) [], CommandNotFoundException + FullyQualifiedErrorId : CouldNotAutoloadMatchingModule
Following the instruction I tried `Import-Module Defender` which gave me:
Import-Module : The module to process 'MSFT_MpWDOScan.cdxml', listed in field 'NestedModules' of module manifest 'C:\Windows\system32\WindowsPowerShell\v1.0\Modules\Defender\Defender.psd1' was not processed because no valid module was found in any module directory. At line:1 char:1 + Import-Module Defender + ~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : ResourceUnavailable: (Defender:String) [Import-Module], PSInvalidOperationException + FullyQualifiedErrorId : Modules_ModuleFileNotFound,Microsoft.PowerShell.Commands.ImportModuleCommand
Again everything was fine some months ago. And by the way the same thing happened on another machine under Windows 8.1 (an HP laptop).
I could really use an advice here. Please help)

... and how is it now? Obviously somethings changed on the system. Anyway that is not a scripting issue. You will have to fix your system.

Well, the thing is this machine is a VM I am only using for testing. So if you ask what happened between the last time I used it and Defender module was fine and today - the answer is nothing really, it was either paused (in terms of Hyper-v) or turned off. Of course some Windows updates were probably installed during my work. Could you please elaborate on the "fix your system" stuff?
