Message Mapping not getting Activated

Hi Experts,

I have done a simple Message Mapping. I am unable to Activate it. The same screen is visible and it is stucked up. When i closed the ESR and again i am trying to activate Message Mapping it is showing the same screen. Even i chekced the Lock overview in Administration tab nothing is locked on my name. Please check the screenshot in the attachment and do the needful.

Regards,
