I installed 2.3.1 30 days trial edition, downloaded just a few days ago from your web site.
It seems that NeT Firewall does not work at all. After setup, I restart the system as requested and when the system is up I get a small window that ask to continue configuration. Immediately after that I receive the message I metioned in first post. After that I’m asked if I wish to abort current instance. Saying YES I get an empty MMC, saying NO the program simply terminate.
What may I check to help you find the cause?
