EMTshooter still not working

I eventually found out how to run "get-user" via exchange powershell and the result was "true"

So, now after a day or geeking around just to find out my account "officially" does have the rights to run commands in Exchange Powershell, I'm still left with this error from EMTshooter:

•   The user account that is attempting to connect is not Remote PowerShell
  enabled. To check if a user is enabled for Remote PowerShell, you need to open
  the Exchange Management Shell with an account that has been enabled,
  and run the following query:
  
  (Get-User <username>).RemotePowershellEnabled
  
  This will return a True or False. If the output shows False,
  the user is not enabled for Remote PowerShell. To enable the user,
  run the following command:
  
  Set-User <username> -RemotePowerShellEnabled True
  

All this is just to figure out why I'm getting the dreaded "HTTP server error status (500)"  when I try and run Exchange Management Console.

None of the solutions available for EMC have helped, although I did find out that WINRM wasn't running and fixed it:

(winrm is running; all ports are open; all paths are correct; all environment variables are correct; IIS is running and listening on port 80)

Any help would be greatly appreciated.
