A while back, I downloaded ZA3 Pro and a keygen. Installed it and it worked OK. I wanted to try Norton Internet Security, so I uninstalled ZA and installed Norton. Well, I want to go back to ZA. After installing, I click Finish and my system automatically reboots, reboots, reboots, etc. etc. etc. as soon as it tries to load. I had to uninstall it in safe mode. Went to their site and I found out that I uninstalled the first install improperly. I did what they said amout deleting a couple of files, but I still have the same problem when I try to reinstall. Any ideas??
