My KMP has encountered a problem

Hi,
My KMP has encountered a problem. I think it was working properly by the time I received an warning message. The screenshot of the warning message is as under. The warning message is throwing while opening some of .ts files.
What does it mean? Have you any idea?
Please help me to get a remedy.

Warning!
Opening Media or URL… Close it forcibly?
Unexpected error could occur!
