Version not working under Windows 10


I have just upgraded my Windows 10 machine to Version 1511 (10586). Now, Comodo won’t work any longer. There is no network activity shown although my browser and my mail client are running (before the upgrade it showed both). I deleted the rule which allowed firefox to access the internet, now it can still access the internet although there is no rule and I told Comodo to ask me everytime something tries to access the internet.

So it seemed to stop working because before all worked well and I did not change anything in Comodo.

Any ideas what I can do?

I simply installed Comodo over the last version and now it works again. Don’t know what happened.
