First of all, thank you all for helpfull replies. I had forgotten the topic, because it was a problem of a friend of mine as i said earlier. I just want to make sure that he gets new unlock rights every week etc.
Thank you all for your help again.
But i need to write something again, for those who can't read, or have lack to understand what they read.
Maybe i should wrote "Or did someone stole his password and logged in from an another computer?" for better understanding, sorry my fault.
I didnt wrote "wherever", i wrote "whenever".
i can lock and unlock my licence on my computer, if i had one. That doesnt make me a licence sharer!!
