Not sure about your problem but honestly I would reinstall Comodo with D+ and leak protection enabled. At those settings your not really protected. Is there any reason you do not want D+ and leak protection on?
I am new to Comodo. I used to have ZA Free. So I just installed the Comodo firewall. I might install Defence+ later on. This machine is too darn slow for one thing, so I have to be careful about any extra load I put.
