Why meeee :S

I think this happens if someone uses Cd Keys you already used before.
/ did you activate a Cd Key which was posted in public recently?

be sure your system is virus/keyloggers/backdoors free.
transfer acc on new email.

Well I tried to activate a key before, but It didn't work because I needed a game for it. So I gave it away. I changed my passwords and emails but they still keep coming somehow. I'm dead scared.. And also scanning every last detail in my pc

Thanks a lot for your help guys, at least I calmed down a bit. I can continue living in peace now. Once again thank you and best regards!

try to change your secret question.

you probably grabbed a key from a public giveaway. other people try that key and when they see it is duplicated, they click on "retrieve account" button. so you will keep receiving mails until they stop clicking on retrieve account button :)

It was mentioned before. And as it was said, nothing to worry about, except for your mail box dying from explosion.
