For some unbeknown reason since updating my PC to Windows 10 from Windows 7 Ultimate everytime I run FSX it asks me to activate it, which I do. However half an hour later FSX comes to a halt and again asks me to activate it. This happens everytime I run the program. Does anyone know what might be causing the issue and how I might fix it.
I also have my original Windows 7 and all of my programs backed up on a second hard drive and wonder if this might be behind the problem, eg some kind of conflict.
