Error: Failed to find .cfg file. [MsgId: MERR-10777]

Hello,

I am having a script in Web-Html/Http protocol, Loadrunner 12.53. I added one new action in the existing script and click on replay. An error message appear “Failed to find .cfg file.”

I click on Runtime setting and save the setting again, but still I am getting this error.

Can anyone help me to solve this.

Thanks
