I received my STC-7 camera & installed the filters. Before I install the SC2 & AO8, I was going to bench test the camera as per manual. I plug in the thumb drive to load software. I click on the Launcher.exe & the installation program starts. I click on the "Install MaximDL" button and what I get is a quick small (DOS) black screen that flashes off right a way. It's quick enough that I can't read what it's saying. I also go to register the Maxim LT software as per the blue sheet in the camera case. My email returns with the subject "Unable to authenticate your request for MaxIm LT" I open the email and there is one word, "Success" I'm in a state of confusion, which is nothing new for me. Carl.
