I also get these errors but I notice this always happening in my case after resuming from Windows Sleep.

Ok, looks like this is due to problems with the timers after the system goes to sleep.
After forcing HPET on in Windows via powershell, Realbench 2.56 will generate valid scores after the system wakes from sleep.
