Azure–Token Error when execute from Powershell

I was doing the following :

• Connect to a Azure from a Computer A
• Execute the connection from PowerShell and connecting to Azure
• Everything was ok.

Then I went to another location.  Executing the same process by connecting to Azure through the PowerShell.  I had no issue when executing the Add-AzureAccount but when I check I tried to get the subscription, I had the error as below :

After some finding, it seemed the token in the second location has expired.  Therefore I did the following :

• The User I login is Administrator, therefore I go to :

C:\Users\Administrator\AppsData\Roaming\Windows Azure Powershell

Note : Change only the value in the PINK, with whatever credential you use to login to the PC.

• Delete all the content in the directory

• Proceed back to PowerShell and Add-AzureAccount
• Then execute the Get-Subscription will display with no issue.
