AzureVMaccessExtension version too high when performing passwor reset via powershell

Hi,

I'm going to reset my VM admin password by windows azure powershell, but failed with the error AzureVMaccessExtension version too high.

powershell command:

PS C:\> $vm1= Get-AzureVM -ServiceName "mikecloudservice" -Name "mikemachine"
VERBOSE: 2:17:14 PM - Completed Operation: Get Deployment
PS C:\> Set-AzureVMaccessExtension -VM $VM1 –UserName "mike" –Password "password.1" –ReferenceName "MyVMAccessAgent" | Update-AzureVM

and the results:

Update-AzureVM : BadRequest: Cannot downgrade resource extension reference VMAccessAgent, from version 2.0, to version
1.0.3 ,for Role: mikemachine
At line:1 char:112
+ ... AccessAgent" | Update-AzureVM
+                    ~~~~~~~~~~~~~~
    + CategoryInfo          : CloseError: (:) [Update-AzureVM], CloudException
    + FullyQualifiedErrorId : Microsoft.WindowsAzure.Commands.ServiceManagement.IaaS.UpdateAzureVMCommand

Do there anyone met the same issue as me and any solutions on this ?
