New 360 layout Help

Computer just updated to new layout (looks good) but icon (on Taskbar) "Solve PC issues" shows "important message action centre".

On opening action centre shows Network Firewall OFF. On checking through control Panel shows network firewall operated by 360 (Checked 360 and firewall shows on) . Secondly the Network icon (on Taskbar) showing red cross although connection to Internet obviously working. What has happened and can you advise. Thank you in anticipation of your reply.
