Second account shows Commodo firewall not running correctly

Been using free Commodo CIS on XP Home SP3. On a user account I have on numerous times seen the Commodo icon in the task bar with a red circle and slash through it. I do a diagnostic and nothing appears incorrect. On my account as superuser where it was initially installed I haven’t noticed that happening.
Have to restart computer to get the second account running. What am I doing wrong? Thanks for any assistance.
