Once you have started the daemon, you need to right click on your project and
run it. After that you should be able to see some samples having been collected.
If not, try stopping the Daemon and check again. The 'Reset session' button just
clears out the current session data. This is confirmed by the error, indicating
no samples were found.

The basic workflow would be something like Start, Run Binary, Refresh, Stop or
Start, Run Binary, Stop, Refresh.

Hope this helps,
