Runing the report, "Client Traffic Stream Metrics" and I get this error

The specified criteria did not match any data for the report.

Make sure that the following background tasks are running:

1.Traffic Stream Metrics
2.Radio Performance

I checked the background tasks and both have a Last Execution Status as "Success."

I forced the "Execute Now" comand on both tasks and reran the report but I get the same error.

Has anyone else experienced this?

Thanks in advance for your help.
