Comodo Crashes and D+ rules disappear

Hello, I have been experiencing some problems with Comodo firewall recently.

One major problem is that my Comodo seems to be quite unstable, and crashes frequently, for example when I try to run the diagnostic tool it crashes and asks me to file a bug report.

The bigger problem which arises from this is that my D+ rules are wiped out after the crash i.e all the rules disappear. Furthermore, I am now unable to select “use a predefined policy” to assign the D+ rules to an application.

Can anyone help me explain why this is happening? Thanks!

Hery and warm welcome to comodo forums!

What other security software do you have besides comodo firewall?
