I cannot judge the legitimacy of the website due to it being in Swedish, even when translated by Google Translate, so I asked what your judgment of it was. There are plenty of pirate-selling websites in English, as well.
Now I will dare to suggest you contact the seller regarding a non-working purchase.
Or you can chat with Adobe about it and see what they say. The link to the chat service, here in the US, is just below the link to the forums.
