I have recently bought the Bismarck 1:700 scale model kit from Italeri (just before they discontinued it) and wanted to redeem the bonus code for the Diana, 1 port space and 500 flags. I find the code, read the page with instructions and on the very bottom of the page there's written: "This code is valid until december 2017". So, did I just basically get scammed?

There are 3 invite codes (1000 doubloons, 7 days of premium), and one bonus code for existing accounts (the Diana, port slot and 500 signals).

Infact the example photo on the website has 20 spaces witch are split into four groups. My code has only 15 spaces in three groups.

Tried it multiple times, still says this: "Unvalid code. Please make sure that you have entered the correct code."
