Activation of SDL 2017 on a brand new computer

Hi!

I bought a brand new laptop and after I installed SDL Trados I wanted to activate my license. However, my SDL accounts shows that somebody else's using my license. I know this is impossible, because I wiped out my old computer completely, including SDL Trados.

I don't know what's wrong, but I would appreciate some help! :)

Best Regards,
