The whole shop Julimarks sells fake License keys. Official transaction statement then suspicious and informal follow up email with "product".
Do not buy from this seller.
If you are finding out after the fact that this was a scam, or unsure if you just cant get your serial key to work. Don't contact them for support. They say in their email that they use Teamviewer - a know scammer program to assist you. Pre-emptively saying its all safe and trying to coerce.
However they say all this when you get the email, before you know your key doesn't work.
