FIM Codeplex Powershell Activity is not marked as serializable?

Hi,

Still struggling with the http://fim.codeplex.com/ powershell activity.

I am trying to provision an Exchange 2010 mailbox - and FIM now shows the following error:

Type 'System.Management.Automation.Runspaces.RemotingerrorRecord' is assembly 'System.Management'Automation, Version 1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' is not marked as serializable.

Anyone have a clue what this means?

Thank you,

SK

PS.

From the FIM server I am able to create a mailbox manually using powershell as FIMService account.

I tested the powershell activity to generate a sample text file, which worked.
