If I understand from your first post, your app (Photo, Designer, Publisher) is not signing in via the MyAccount? You did try running the app as Administrator? This seems to be working for about everyone. It's a workaround until Serif gets the problem fixed. When's the last time you rebooted your system? In Windows, select Restart from the Start>Power menu. I didn't realize until recently, Restarting is the preferred method of getting a good clean bootup, not Shutting down, then starting. I guess they've made all the recently releases, where when shutdown, a lot of things stay resident in RAM, (TSR), so is not flushed at shutdown, more like the Sleep or Hibernation modes.
