When i copied the three resulting keys out of steam back to the account page it said two were invalid. . The two addon aircraft from the deluxe pre order pack. I CAN GO NO FURTHER and cannot login.

p.s. I ONLY had one license key to start with and when I used the steam key it split them into three

I wonder if anybody else that pre ordered is the Same here.

It's probably an outlandish idea but, have you considered contacting support?

I believe this kind of issue is just what that page is designed for.

I did the same then went back and realised that I had copied the 190 key into the LA5 and the LA5 key into the 190. A straight forward case of not paying attention.

Exactly what I realised I did at 1am in the morning.
I was too tired to pay proper attention. The extra aircraft keys were flipped in opposite order in steam to what they were in the il2 page.

P.S. Extreme_one I had contacted support and just had to send apologies to them. (no I did not abuse them just feel I bothered them for my own stupidity)
