The problem appears to have been junk or corruption in the Windows Registry for the Parallax SX-Key. If you are comfortable using regedit (messing with the "hives" of the Windows Registry), this problem can be fixed by deleting the "SX_KEY" entry and children from "HKEY_CURRENT_USER\Software\ParallaxInc\SX_Key\2.0" . After this is removed, the SX-Key software can be started and the "first run" messages will appear and the COM port and other configuration settings can be set. Since I did this, the SK-Key V3.x software has been "rock solid".
