Do I need to reinstall?

Hi I updated to the latest version of COMODO firewall, but people are saying that they are getting failed leak test. I did stealth ports with the option in Comodo, I cant do a leak test because forwading ports on my router is complicated. Should I do a clean reinstall?

I think it should be fine but if you see that it doesn’t work as it should then uninstall it, clean the registry with CSC or any other and reinstall.

My personal recommendation is that you install CIS and then Immunet.
