The latest upgrade is crappy. it broke the firewall

The latest upgrade (the one with the new look of the notification) doesn’t seems to remember my previous settings. it blocked me from using a remote admin tool and so it locked me out. I had to have someone check the 'trust… + checkbox and hit allow. and that prompt keeps coming up and therefore I am still locked out.

now I have to uninstall the whole thing and revert to the older version.

Or you just configure the new Version as your old version was configured and you are good.
BTW. you swiched from version 4 to 5 so you just have to do some work configuring.
You also lost your setting by switching from 3 to 4 so nothing unusual happened.
