I just loaded the Scottradeelite stock trading platform on my new computer Windows 8.1 and it will not launch. Actually, it launches sometimes. It will work for a week or two and then it just won't launch. There is no error message. I read on the internet that Scottrade recommends adding three exceptions to the firewall. But I also saw where Norton said this should be done automatically. What is going on? How do I add exceptions?
