Workflows throwing Object Reference Error RRS feed

  • Question

  • Hi All,

    I am not able to open any of the existing workflows in the CRM 4.0 environment. I get the below stack trace on opening or triggering them on an entity. 

    I have tried IIS Reset and restarting async service. This did not help.

    Below is the stack trace. Can anyone make out what might be going on and how to fix it? Thanks
