I purchased Jammer yesterday and installed it on a win2000 prof system. When I reconnected to the isp today, Jammer didn't work all day. I tested it with Symantec security test and the zonealarm firewall log showed the attempts. Jammer was silent and nothing was in the logfile.
I tried disabling zonealarm and shutting down jammer and restarting jammer only and retested with Symantec. Nothing was detected by jammer even though the status line in jammer showed the incoming packets.
Also the Jammer trial ended the 2nd day of the trial before I purchased Jammer. The inability to copy stuff from jammer is a real bummer also.
