Edit: SORRY, didn't saw the attached thread about it! =x
My hardware ID is changing a lot and I didn't do anything on my computer, only shutdown and on again.
It happened 4 times in 2 days, one of these times it changed and then changed again to the one it was before.
Yes, I'm running as Admin, I got windows 8 64 bits but it is not the problem cause I've used it for some time already and didn't have any problems.
What can I do to solve this? Will I get back the days I'm losing on my account?
