Last night, the ControLinc was not in My Lighting after several attempts to link to it. In addition, the event viewer would not open up. I shut everything down last night and when I opened the adminsitrative control panel, lo and behold, it was there. Then I tried opening up the event viewer and it opened flawlessly. Maybe I was too impatient waiting for the ISY to locate the ControLinc. I don't know but it is in My Lighting now. Thanks for the suggestions.
