ksp won't show up in product purchases, can anyone help?

[Zanman248]

I recently purchased ksp hoping for "purchase, download, play" but I got "purchase, nothing" the link wont show up in my purchases and I am highly concerned. If anyone can help me retrive my $40 in the form of endless rockets, that would be great, thanks.

Where did you bought the game? In the KSP store, steam or gog?
Have you checked your bank account if you actually paid for the game? Maybe something went wrong.
Have you already tried to contact the offical support?
