MII 12.1 Workbench Error - Content Could not be parsed

Hi Experts,

I am facing some issue with MII workbench. When I try to open an existing transaction or create a new transaction I am getting an alert message with error as "Content Could not be parsed". I have attached the screenshot of the error.

I am using MII Version 12.1.5 Build(99)

Any help on this very much appreciated

Thanks & Regards
