note: i re-ran aida64 with the task manager closed this time and so far i don't see that error message. (my previous post had task manager running)
i will let it run overnight and i'll see the result, but i think ALL programs have to be closed, including task manager.
i too get the same error.
after this message, AIDA64 does not update the CPU load percentage, but temps are continuously updated.
(windows 10, aida64 latest version as of 10/1/15, i7 5690)
