Screensavers and Comodo Firewall

I have an external screensaver (other than Microsoft) which comodo firewall has listed as safe but yet will not allow it to run. Infact I am not able to run any third party screensavers even if they have been declared safe. I disconnected the internet and disabled comodo firewall and the scr was able to run as directed. How can I fix this?

How exactly did you disable?

I unplugged my cable modem then right clicked on the comodo icon in the task bar and clicked exit.

Can you post a screenshot of the D+ logs? They are under Defense + → View Defense + Events.
