I am using windows 10. I have requested tech support but they will not address the issue. No error messages appear when it starts to load and then flickers on a white screen then shuts down. I have uninstalled it and reinstalled it so all is on the primary operating drive, I have taken screen grabs and sent it to tech support. But their responses take up to 7 days and they seem disinterested. What use is a program that will not work and one not backed by a money back guarantee and very little in the way of tech support. I should have stayed with Pinnacle.
