Files become hidden after an error with CPU-Z

Hi. Please help me solve my problem with CPU-Z.
I was in the middle of my work when this error popped up saying: An error occurred when opening the driver.
CPU-Z will launch but not all information will be available.
After that error some of my data becomes hidden.
I tried restarting my computer and it would work smoothly in few minutes.
But after that, the same error message popped up again.
And I need to restart my computer again to make it work.
Please I need some help.
