Ok, so it sounds like your issue is different. Do you have a few minutes to help troubleshoot this issue? If so, could you check to see if Joulescope created any log files? Use Windows Explorer and navigate to to your hidden AppData\Local directory:
C:\Users\{username}\AppData\Local\joulescope\log
But replace {username} with your username. My Win 7 skills are rusty now, but I think that this still works from the command line or start bar:
explorer C:\Users\{username}\AppData\Local\joulescope\log
If you do see a log, could you copy the text here?
